Will This Truck Pulled by a Magnet Move?

- A truck with a steel plate connected to the front is pulled forward by a magnet. However the magnet is connected by a rigid beam which attaches it to the truck.
Ultimately the magnet is going to pull forward on the truck, but the beam is going to act backward on the truck, meaning the truck will not move forward.
Sometimes though, I just wish the troll logic would actually work and just shock everyone lol
I know right? 😀
Wrong construction. Not like that.
If the magnet pulls the car toward itself (>), it is also pulling itself toward the car ()(
Precisely.
What if one magnes is "stronger" or something like that?
Think of it like this every magnet (no matter how strong) will create two movements.
The stronger magnet will pull the truck to itself AND itself to the truck.
This then cancels out the movement.
The stronger magnet's own power will prevent any propulsion.
Even if the stronger magnet had infinite power the truck would still not move.
@@tdx656
@tdx656 the bigger the magnets the stronger the pull
having one smaller magnet would just make the pulling force weaker so really nothing would change

Newtons first law: an object at rest will remain at rest unless acted upon by an external force, all forces will cancel each other out regardless of the setup
This.
Give it some gas
Even though I've always been pretty good in Physics sometimes you forget the basics and need help.... you explained it pretty well :D
If magnet is suspended in air via some kinda magnetic field, then thr will be no force to pull truck backward...
This theory is failed by gasoline mafia.
Great explanation, thank you!
Nice explanation , thanks a million
Glad you liked it
I made a car for my daughters science homework. All the kids had to make this and I used an ordinary toy car about 8 inches long and put a mouse trap on top of it with a string attached between the metal wire on the mouse trap and the axle of the car. It didn't work very well. But even with no string attached the movement of the mouse trap wire in a semi circle from the front to the back of car, imparted forward velocity to the car. The car should have moved forward as the wire of the mouse trap moved backwards in a semi circle and then the sudden stop of the wire should have imparted the equal backwards motion to the car but it didn't. The car kept moving forward. I could not figure this out. Still can't. Momentum was not conserved. The whole car and mouse trap together were in a stopped state at the beginning and should have been stopped in almost exactly the same location at the end as the mouse trap triggered. The car should have moved forward and then backwards back to the exact same spot. But the car in real life went all the way across the room.
If you did this in outer space and a weight inside a closed space ship is thrown from one side to the other, the space ship will move a bit in the opposite direction and then stop in s slightly different spot because of the center of mass being moved.
Homie really said pushing on the steering wheel is the same as this magnet concept. Bro what? No it absolutely is not lmao
What if you had a rotating front wheel where the front magnet would be 8 magnets that all face outwards. So it wouldn’t constantly be pulling, it would have a pull and release effect.
Also, inside of the 8 arms that the circle of magnets are attached to, there would be bearings inside of each arm that would fall forward from centrifugal force as the circle rotates.
Dang. Newton really screwed the world with all these laws he made smh
Just mount a giant magnet to your neighbours car when they're not looking. Problem solved.
Consider my theory: it is not the "magnet" pulling the truck but the invisible magnetic interactions. THERE IS AN INVISIBLE MOTOR INTERACTION that does not come from a force of the magnet itself but of the distance between the two parts in interaction.
huh
So if you can find a way to reduce the tension on the beam to a point that the magnet has more force on the steel plate than the beam has on the the truck then it would work? (sorry for my bad vocabulary in this question, i dont know much about this. im just trying to reason through it.)
Thank you no more car accidents 2024
Great explanation 👍🏻
Thanks! 😃
But what if i removed the beam and Levitated the magnet with a second magnet underneath the first one?
Now we're talking external forces on the system, which works.
How would it move?
@@jackjackbt with magnets
If I attach a magnet to the base of the truck and extend a magnet outward then levitate another magnet and get it to pull the truck, can the truck still move forward?@@INTEGRALPHYSICS
ignoring the fact magnets dont work at right angles, how does the "second magnet underneath" move forward? or does the car reach the magnet and just stop?
thanks for the explanation
You're welcome
cool explanation. now how can we make it work?
instead of having the magnet infront of the truck. have one infront of each wheel and an upward angle which would cause the wheels to roll. hope this makes sense. just a thought
Funny to see these kind of things in cartoons and then compare them with the real life physics
What if the magnet was propelled itself? Imagine if you will a locomotive in front of a train of railway cars being pulled by a massive magnet. Of course that magnet needs to be powered, but if the power is more efficient than diesel (for example) there would be value there.
You make an important point that most people miss... Somewhere in the system you MUST have some form of engine producing power, and that power/energy has to come from somewhere, but at the end of the day its the efficiency that's key.
Just change steel plate to another magnet and replace the bar with a chain of those tiny fridge magnets
Omg I just unlocked a childhood memory of me trying to make this as a kid
I have a question. Though, instead of attaching a magnet to the car, what if we use a paper clip?
i want someone to try this in real life, I wanna see this live
The law of conservation of energy states that energy cannot be created or destroyed, but can be transferred from one form to another. This law is based on the first law of thermodynamics
Way back in the late 60s and early 70s when I was in school taking my first electronic class, electrical flow was illustrated using a water hose as the conductor, the water flow as current and the water pressure as voltage. Today physic's knows that electrons do not orbit like a planet but pop in and out of their shell orbit. Question, could you explain electrical flow as you understand it today? And how does wave frequency play a role?
Good I figured that was the case.
Then just put the magnet on the truck underneath the truck, and create a road full of other magnets that push the truck forward along its track. Pretty simple. o_O
Just a maglev train, but for cars!
What if you were to make the arm holding the magnet made out of magnets, so it’s not actually connected to the truck? If I go missing for my mother, I love her.
Since the studied system (solid indeformable) is the car + beam + magnet, the force between the magnet and the car is an inner force and therefore does not intervene in the fundamental principle of dynamics, so has no effect on the movement.
Is that all right?
Something tells me you may have studied statics before... Well put.
So what if the design was different to where there was many magnets in a wheel like structure and one half was connected to the axle of whatever wheels would be moving and the other half are connected to clamps that made the magents clamp closer together to apply that force, wouldnt it be able to start moving the wheels due to there being no backforce, so instead of it trying to push or pull the car its just applying directional force to the wheels, if that makes sense
And then I feel like there would still be a viable way to send power to the alternator to keep the battery alive
What if you had a lead car and set this up like a train car system but only used one vehicle to start the others in tow ? Not that it would work for road cars but how about a lightweight train or a rear car repelling pushing it forward
If we’re talking about a magnet big and strong enough to move an entire car, wouldn’t one end of the beam that’s attached to the car end up tearing right through it as both magnets smash together?
thats nothing compared to what would happen every time you pass a biker...
Why not replace a part of the crane with a spring and make the magnet an electro-magnet, that way when the electromagnet is turned on by some current, it coils the spring and touches the Metal on the car, then the current can be turned off and the potential energy in the spring propels the car forward. the current supplied to electromanget would be minimal with the maximal energy created by the spring, hence it is efficient.
Good idea, it would make the car move momentarily then stop and return to its original position as the spring rebounds. In the absence of a force external to the car/spring/rod/magnet system, the center of mass of the system is not going anywhere in the long run.
So if i understand this right i could get a different truck with a magnet on its back to pull another truck?
Then you'd have a magnetic tow truck.
Stupid question - What if the beam was mounted onto the plate and not the car ?
same outcome
We should have big magnets 🧲 on each traffic stop 🚦 to pull-push the cars and give it enough velocity to reach the next traffic light 🚥
😅
😮
So we could significantly reduce the power needed frome engines by assisting them with magnets?
Troll Physics classic
Push the handlebars on a bike forward. Same thing. Or put a rope around your waist and pull it.
Well put.
If the last part attached to the magnet is a thin rope instead of a rigit pole it could work
It doesn’t matter what it is
Also a role isn’t rigid enough to hold such a powerful magnet
Thank you so much
No problem
if only the magnet wasn't attached to the car, if only but alas it's not like it's possible
The issue with permanent magnets, I don't care where you put them, is that they act like springs. They aren't a source of energy, they simply store then return energy that they have been given; Meaning you still are going to need something to do work on the vehicle.
@@INTEGRALPHYSICS imagine if roads and highways had a magnet conveyor belt above them
Twitter suggested this😅
What's missing here is the explanation that the force of the magnet needs to be equal force to the weight of the truck and occupants plus gravity.
That's easily achievable when your using a small scaled model that's under one pound in weight. Try it with a several ton vehicle and see how heavy your steel plate and magnet need to be without interfering with outside forces like your cell phone or other vehicles in the road. No one entertains the interference these magnets would have in abundance on the road.
Only if we were trying to lift the truck. A typical car engine does not produce a force equal to the weight of the vehicle, that would correlate to 0-60 in about 3s...
Physics teaches you how to make things work!
The problem is all those people who don't know any physics...
Hmm the best way i understand it is ... If the magents on the car and the magnest arm were the same pole.
Would the car reverse or would the forces push each other and snap the stick in thr middle
Removes the whole idea of tensile strength holding the magnet in place
Or just
With that setup.. if i push the magnet with my finger will the car move ?
So if that happens why won't the car push itself back
You already believe it can pull itself
Lmao it doesn't work cause you can't even see where you're driving 😂
I have a question about chariot, the horse is pulling forward and the chariot is pulling the horse backwards but its still going forward, I guess it's because both horse and the chariot are on the ground and relative to ground their both moving, right ?
I kinda grasp but can't fully understand
The horses push forward against the ground creating a net positive force forward. The magnet is not pushing against anything that would create a forward momentum for the system.
@@lt3880 thank you,
Kinda understandable but still not understandable :D English being my third language is also not helping
Anyway still thank you !
get two trucks and put one with a magnet on the back in the front, staying close enough to the one in the back for it to move
21ST century tow truck. nice.
Hmm if the problem is that its all anchored to the same point could you not counter that with ball bearings to separate the two objects or use a bring to absorb the shock and regulate the whole process? Just looking at it makes my mind explode with millions of ideas on how to actually get it to work, the problem is that your doing it way to simply
What if the magnet swings?
Would it work if you use a big ass drone? Which is basically a helicopter and I just realized... I hate us gen z
So it works if we invent telekinesis.
So it would work if we had a device capable of creating magnetic fields at a set distance from the truck repeatedly.
The magneto field generator. MFG. A standard issue part of every “verticar”
INTEGRAL PHYSICS, what if you had electric magnets in the roads that turn off and on at the right time and had steel in peoples wheels (however you could get that work correctly) and had your car moving that way?
that works.
I guess, then, if there were a series of magnets held in the ground we could move the car though a road. I guess thats not very different from a car going downhill, being pulled by gravity
Now if there was an electromagnet in the road, that moves down the road pulling the truck forward the it would work. Like a conveyor belt
Every action has an equal and opposite reaction, so for the car to move forward there needs to be a force pushing backwards against the road (like tyres) or air (like a propeller). There is nothing in this diagram to push backward, so of course it cant move
That guy Newton and his stupid laws. Make our life difficult.
Yeah, in the sense that everytime you change the laws of physics in an interesting way, everybody dies. That would solve all our problems, kind of.
That is the intuition I came away with reading a couple of What Ifs on xkcd. Might be stupid.
New sub
Well , if that doesn’t work why don’t you do the same thing but backwards and instead of attracting it repels
We can put the connector between magnet and truck
What about the force of gravity? How would that change the situation. We have take all major forces into account.
Force of magnet and car, force of gravity and friction of tires.
gravity is straight down, it does not act in the direction of motion.
Doesn't that get cancelled by normal force because it's not moving anyways?
@@GozieaaaThe force cancelling out gravity is the force that's holding the car to the ground, called the "normal force"
Rather try it because it works.
Same thing as trying to lift a chair while sitting on it, doesn't move
Well put.
@@INTEGRALPHYSICSShut up!
In 9th grade shop class we had to do our own projects. One student made a wooden high speed train on tracks using magnets. You just shoved it and the magnets propelled it along the tracks like a bullet. So yes it worked as long as you gave it a shove. Inthinknitnstoppedna few times but the magnets reeally did propel it. It floated on the tracks.
That's a separate magnet that's not connected to the train
@@kirk5649 One was glued on the bottom of the train and another string of magnets glued on the track of opposite polarity. It looked like a high-speed bullet train. And the speed train was held in place by the track.
@@MARINE76911 yea that's what I'm saying. I've seen one too. It works if the magnets propelling the train aren't connected to the train
This is the exact same thing as using mounting fan to move a sailboat
but there ARE boats (or those glider things) that use a fan!
What if the beam was in the middle of the steel plate
nope. you need an outside force.
What if you put a weight on the magnet holder
nope, you need an outside force acting horizontally on the truck or magnet.
So what we have to do is use magnets to create a beam that does not touch the truck? Fuck they’re gonna come kill me.
Instead of the simple example why not just test it out full scale
Good ❤❤❤❤❤❤
Thanks!
Make a physical example and test it.
It would cause a crime if it worked
So then explain to me how I'm able to push a car while it is on neutral if the force that I'm creating is being met with an equal and opposite force
that works because cause youre pushing against the ground. put the car in neutral, sit in the drivers seat, then push forward on the steering wheel... you wont go anywhere.
You are really dumb, forreal🤣
just break the law .. its easy
It still doesnt make sense to me. Why is the beam pushing back on the truck?
Perpetual motion machines don't have to be infinte, if we can harness one for 1000 years that will do. Why can't gravity as a force be transformed to create power?
Not to be an ass but a perpetual motion machine by definition is infinite.
To address your real question, we do harness the force of gravity to produce power (ie.hydroelectric dams). The problem which arises is that in order to produce energy you need more than force, you need that force to move something over some distance. In the case of a dam it's water thats pulled downward by gravity, if you go sledding its your mass that gets pulled downward...
The issue in both cases is that you need some mass to start up very high; and it takes energy to get that mass up high. The nice part about hydroelectric dams is that its the sun that lifts water vapor upward. Unfortunately when sledding however, you have to hike your butt up the hill.
@INTEGRALPHYSICS i suppose it's impossible to create an infinite machine that will never need a tune up and that will last for infinite years. No materials last forever, even if the concept could produce energy infinitely.
Thanks, yes I see now some dams use excess energy to pump the water back up also. I guess that's using the force of gravity but not actually containing Gravity itself as a force to be transported and used elsewhere, if you catch my meaning
So the solution is to remove the beam and have the magnet float in front of the car. Duh!
Its possible... hard plastic rod. And plate the magnet concentrating the energy towards the front of the car. And a plate behind the metal block. Problem solved
I am starting 6th grade - what is a magnint?
Rules are meant to be broken
good luck
but what if u replace the steel beam with another magnet...
one magnet following another magnet in a closed ring- case. the ring case is magnetic on the top and bottom, so the moving magnet consisting of a top and bottom repells it from touching the case while the front and rear magnet parts cause it to travel around the ring and a side facing magnet is directed at a copper coil around the sides of the case... profit?
& one magnet is stronger than the other
sorry i try to delete
newton missed 99 calss
Bigger magnet??
Beam that doesn't move? Guys i feel retarded wtf
The issue is that the magnet is doing two things at the same time. The magnet is trying to pull the car forward AND the magnet is trying to move backwards to the car. If you were holding the magnet instead you would feel the magnet try to drag you to the car. That force ALSO is what's ruining the situation.
If you put the magnet on a wall that force doesn't go away. The wall us just strong enough to keep the magnet still while the car gets pulled.
On the pole as pictured, the CAR is getting dragged forward and backwards. Adding more power doesn't matter. So long as the magnet is attached to the car it'll balance.
^^This
then what if the magnets are in the road
that exists in some train systems
Theory. Show the practical.
What's wrong is you not doing the test & just pointing to a picture saying words
Get stronger beam. Simple
You're doing it all wrong dude. The one I saw didn't have a steel plate on the front. There was another magnet with opposite polarity. Total different setup.
What difference would it make? All the forces cancel out regardless
What if they where opposite
Pls reply!!! What if one plate consisting of multiple magnets placed in a circular pattern and that is being driven by a motor but in front of that plate another magnet is there consisting of a same like poles ; *NOW NORTH VS NORTH POLE IS FACING EACH OTHER AND HYDRUALICALL Y WE ARE MINIMIZING THE DISTANCE BETWEEN TWO PLATES......WHATS GONNA HAPPEN THEN??*
From India ❤
I don't care what the setup is, unless some OUTSIDE force acts on the car / arm, that car is not going anywhere.
@@INTEGRALPHYSICS yes sir, but if we provide a driving force in the name of external force only?? .......if you say I cn show the designs!! Just being a science enthusiast ....so I asked
You either need something stationary to push or pull off of (think a tire pushing against the road or a stationary magnet to propel the car), or you need to shoot something out the back of the car (think a rocket engine).
@@INTEGRALPHYSICS sir that magnetic plate will be rotated by an electric motor which will b fixed on another magnets top floor....there will be a stationary part but will be in rotating sense
ok fed
Bro, you're HOLDING the rubberband on one end, smh. Big difference when the opposite end is on WHEELS, lmao. By the way, it DOES work. I don't know how practical it would be with a full size vehicle but I made a tiny wood model car with this magnet setup some time back & placed it on a level surface. Believe me, it works. This guys is reaching too much & you can tell by how he tries to explain it, crutching on Newton's Third Law while ignoring the fact that this idea involves free motion.
holding the rubber band represents the beam holding onto the magnet, thus the attraction between magnetic force is cancelled by the beam holding them apart. there is no such thing as free motion.
Ok I don't get it thanks
It worked but it got patched
car company working very hard to try and keep selling their crappy cars
So why does it work with toy cars?
it doesnt... unless you include that dude on youtube who has an entire channel of perpetual motion machines.
