I can't help but feel that the steel sign that says magnet on the other side of the wall is blocking the full potential of the magnetic force. It's like when you purchase strong magnets they are shipped sandwiched between steel disks so they don't stick to shipping containers. Please revisit this one without any steel between the magnet. The rebar is fine but the coragated steel on the outside and the steel plate on the inside could seriously effect the force imo
I wish they could do it again with out the steel as well. That being said the steel probably didn't do a lot, maybe cut the effective distance by a few cm at the most. However, their magnet was far closer then in Breaking Bad and still didn't have anywhere near the same effect. Magnetic force follows the inverse square law, ie every unit of distance you are from the object the force is divided by the distance squared. So the drop off of magnets force is rather close to the magnet. It was probably never going to work and if it did it would've been no where as destructive as the show (maybe flip a few bits on the disk at best)
An electromagnet used for lifting will generally have a housing designed to concentrate magnetic flux in the space immediately below the magnet. Any magnetic flux that goes completely around an object being lifted will be effectively wasted, and it's generally desirable to have objects which are being hoisted not grab all nearby objects they move past, so a design which concentrates flux will make a magnet more useful for lifting. If the coil could be removed from the frame, the magnetic flux from a bare coil would be much less dense, but reach further, than the flux produced by the assembled magnet. Further, junk yard magnets are designed to be operated continuously, but for purposes of the myth what would matter would be peak magnetic strength. Even the coil would melt after a quarter-second of operation, it would either have done its job or failed to do its job, rendering continued operation irrelevant.
Wait, is that Allie from Tech-nic-Allie Speaking? I love her content 😁
The chair worked - the door failed.
Once again, the door was the failure point on the second and third test.
That's the problem with construction - you can have the best locks, the heaviest door, or even both, but if there's any weak point in the system - the frame, the hinges, etc, then you get a failure - a chain is only as strong as its weakest link.
As such, the chair - or one of those devices you can purchase which is an aluminum bar with a rubber foot and a V at the top to act like a chair - can only slow, not stop a determined intruder, due to there being too many weak and potential failure points on the door itself and the frame.
That's fine though as unless you're in a room you can't escape from, that slowing down of the intruder gives you time to escape, call for help or arm yourself and while you can get in trouble for firing blindly through a door, even if someone is in the process of kicking it in, once they come flying through that door and are trying to regain their balance, they are fair game to do a mag dump on.
mythbusters an mythbusters jr was such a blast to watch .
The data wasn't wiped by the magnet; the magnet made the heads of the hard drive crash.
Indeed, for purposes of the myth, what should matter is not whether the drive is damaged to the point that it can no longer read data, but rather whether it is damaged in a manner that would prevent data recovery by a firm with specialized tools and expertise to deal with physically damaged hard drives.
Do American houses have cardboard walls and sawdust doors? No wonder tornado alley exists.
New houses are indeed built with sawdust held together by wax. Look up LP Smart Side.
The much smaller magnet weighs 3000 #s! The Dominoe 6X Bigger only weighs 2081 #s
I don't think that domino was really 2081. It sounded hollow when it fell, and the wooden palletts were not completely destroyed.
@@GermanSausagesAreTheWurst A solid steel block the size of that domino would weigh much more than 1000kg.
pls paper doors 😂
awww. RIP Grant.
They should test Knives Out: Can magnet destroy VHS tape?
I haven't watched the movie so I don't know what size and type of magnet is used. But a magnet like the one they used in the small scale test would effect a VHS tape and most likely make it unreadable at close proximity
@@A_N1ne A small magnet from a door of a refrigerator to stick some notes on the door.
@@AndrewNiccol that size of magnet, direct contact to the tape itself might do it
