@@cheesecakelasagnaTo me, at least, it's the difference between engineering and science: How to do it vs What is happening. And the "Why do it" is simply philosophy.
My friend brought one of these to school once. He got it stuck high up on a metal doorframe where he couldn't reach it to turn it off, so he jumped and grabbed it, using his own body weight to tear it off. Well, not only did the magnet come off, but so did some of the paint from the doorframe.
The latex paint has poor adhesion to begin with. The magnet pressed against the frame so hard it caused the latex paint to adhere to the magnet (like masking tape). If you get your friend to try the same thing with an Oil Base Enamel coated surface (like an antique railing) the magnet will pull away clean
I remember a company possibly I don't know... 10 plus years ago creating magnets like this with complex designs for all sorts of application. Seen it actually on History or Discovery. So you know it is old. They made it sound revolutionary, but people are saying this tech has been around for a while. So I don't know what gives. Maybe it had to do with the manufacturing process or the complexity of the magnetic fields. They did make a big deal about both. It was mainly about making locks.

Without watching the whole video I'm gonna guess there are two magnets and you simply rotate them so the interference pattern is either constructive or destructive. Nailed it.
@mygaza Constructive Interference: The forces of the magnets pointed in the same direction combine to exert greater magnetic force. The magnetic contraption is "on". Destructive Interference: The forces of the magnets pointed in opposite directions (the push and pull) weaken eachother-- in this case, effectively cancelling out the forces. The magnetic contraption is "off".

Door mag latch (inside the strike) is usually a solenoid plunger. Mag Latch is usual a unit outside the door, inside the secure zone with a steering electromagnet. System can energize, de-energize. The main reqson they can't rely on this method is safety. The system can't rely on any mechanical means in case of fire. Door bars qualify because they can be activated entirely inside the secure zone
He's probably on about the locks that Google results show when you search "door mag lock" and they don't work in the same way as this device does, they're electromagnetic with no mechanical components.
The ones I’ve seen actually put a short between the two poles. These types have a little rotary switch and you just turn it 90 degrees. Prob doesn’t “turn off” good as this one but they will turn on and hold hundreds of pounds and turn off and easy to lift off the steel table again.
NASA developed magnetic "gravity" boots way back in the day that confused the hell out of people as they switched on and off with every step. Alot of research on mangnets has been done focusing on shape/geometry of the magnet as well geometry of magnet placement to direct/redirect manetic field lines where wanted/intended. One form is a gate/valve, pass/no pass configuration. These are NOT EM magnets, but the same principles should appliy there. Its just easier to turn off current if you have the power.
The first time i used one of these was a drill press fence in my university's shop I was absolutely floored by it, as soon as i got home i was googling how they work lol
Fascinating to consider how it doesn’t take force to turn the magnet off, despite it resulting in the metal bar leaving a magnetic potential well. I think it’s because the two halves are more stable in the “off” configuration, which offsets the force needed to pull the metal bar away? It’d be interesting to know if turning the magnet on is difficult (with no object attached)
You can watch the original video to see him turning it on, he does so with a 3 finger grip and it doesn't seem to be much work. So I'm not sure that either config is "more stable" my guess would be that they're equally stable and that the offset comes from the unique interaction between the off configuration and the steel side-walls.
@@Nezxmihe meant turning it on while holding the piece of metal to the magnet. Not simply turning it on with nothing there. Also, weird that he clicked that he loved OPs comment but didn’t respond to it. I’d like to know where I can get one of these so I can try it for myself
Turning the magnets require a force like trying to put 2 magnets close and then pulling them apart, is not a huge force because the magnets are small and the device probably offers you a mechanical advantage like gears or smith also altho it can hold the bar it can't lift it and the small pieces barely have any potential energy
In a machining shop I used to work at we used these attached to winches that were connected to rail systems on the ceiling so you could lift up a 1000 lb bar of steel and easily carry it anywhere in the building. Super useful devices.
