Lenz's Law states that the direction of the induced current will oppose the change in flux that created it. Here's how that looks in practice. For more videos like this, subscribe to @veritasium.
@@testacals The more force you apply, a counter current called eddy current starts being generated which heats up the metal due to resistance. So if you apply enough force the current will be high enough to melt the plate lol
@@glyph303 at that point you go through the hero arc after being defeated so they set you up with super conductors to keep going to reach your true potential.
@@meraculus-zn3zx The larger amount of force you put into this system, the more it gives back directly against you. You cannot become strong enough to overcome Lenz's Law, only the material limits of the thing you're trying to move.
Cooked kaisen is very good manga, "nah I'd win" is not the signature of the manag but the cooking arc is , will all now our brother are cooking at the finals .
Physics: I see what you're doing. Well, I wont just stand here and do nothing. *melts the plate while laughing maniacally* You thought you could bring me down? I'll just bring down myself instead! MWAHAHAHahahaha *fades into oblivion*
@@rampagingsasquatch5847 If I were DMing my PCs going against this thing in the video, it taking 5 minutes and them having rolled a 12 would probably be the optimal scenario for this lol... (Because you could interpret rolling high as just exerting more force, which is obviously bad haha)
Lenzs law is that induced voltage is always 180 degrees out of phase from the applied voltage. Which also correlates to induced magnetic fields that out of phase voltage causes the magnetic field to oppose changes in the magnetic fields meaning you cant change them until the induced voltage is removed. And this honestly is an excellent teaching demonstration to show how it works in realtime
This is the basics on how a coil works. During my bachelor studies on Telco Engineering, an electronics lecturer used to explain that as the "prick-tease" principle, "come get it, oh you don't"
Sometimes there's just a random explosion from the air that should have been in vacuum examples too, and non spherical extremities of cows raining ftom the sky
I’m an MRI technologist. We had a pizza pan that we would let kids play with in the magnet. It was cool to watch it slowly tilt into the magnet. Took over a minute to become parallel with the scanner table.
Really is. Such an exact example of what it feels like. It’s so difficult to explain accurately, but this couldn’t be more precise, even the part where he stands on the metal square for a second and it momentarily speeds up, just to get stuck on slow motion again.
The mechanical analog of magnetic induction is mass. It's inertial; opposing change. Friction is dissipative and is most closely related to resistance; it's a mechanism of energy loss. To complete this commonly presented picture, capacitors and springs are analogs and both store energy. Or to compare them to inertia, they take in, then release the changing quantity. In many systems where energy propagates through a medium, it's useful to identify a similar pair of "reactive" concepts which describe the energy being continuously balanced between change-opposing and change-storing actors. These concepts together define the medium's impedance, propagation velocity, and resonant conditions. It's a very useful and general framework.
@@ericwtfsky Watch Veritasiums full length videos. He explains scientific principles via demonstrations like these and other entertaining means. He completed his doctorate in science education. Schools definitely should be using his teaching techniques And as for when would we use this? Learning science is not just about a single piece of knowledge, its about learning how to acquire knowledge in general. To understand why this is read Karl Popper whose philosophy is the very bedrock of our modern scientific endeavor. As Popper makes clear the way we acquire knowledge is the same regardless of what knowledge we gain, it applies to all subjects. So learning to acquire scientific knowledge is just learning how to acquire knowledge in general.
Isn't that true for anything though because of inertia? Pushing and pulling a box forward and back, there is resistance both ways. It's just that weight machines are usually built up and down, so gravity makes one way much easier. But you can just pull and push a box of nails with a rigid stick, and it'll be what you want.
@@icodestuff6241 Im not too sure if I understood wym, but my point is basically that this things resistance increases proportionally with the amount of force used. With regular weights, there is a constant amount of resistance.
The harder you try, the harder it is, but as long as you keep trying, you'll eventually get there, no matter how slow. Because Lenz's law only slows things down, it doesn't stop them completely.
@@deang5622 that is the exact same effect, just in a environment with zero resistance. you can already see that aluminium falls faster then a copper plate does because the currents induced in the copper are higher
@@daktus05 Quantum locking is NOT the same effect as Lenz Law. Quantum locking only occurs when the quantum mechanical effects kick in which cause zero resistance. Lenz's law is nothing to do with quantum mechanics, it is a manifestation of Faraday's Law of electromagnetic induction. Faraday's Law says: e = dϕ/dt Lenz's Law turns this into: e = -dϕ/dt It introduces the minus sign. 1. There is nothing quantum mechanical about it. 2. There is nothing temperature related about it 3. It is nothing to do with resistance and nothing to do with zero resistance.
This good be used as some sort of shock absorber for cars or sound proofing, vibration isolation in commercial/industrial or even a residential setting
@@ravenn8600 Our body is working with some kind of electrict current going through it (nervous system, heart beat timing). Whenever you have any kind of current in a magnetic field it will be affected. I guess there must be some kind of effect.
