Demonstration of the true LENZ's law

YouTube - who can explain this?

Hello man,

The explanation i heard is that the magnet induce a current in the super conductor and thus it floats by the repulsion lenz law. Is like when you get a neo magnet and quickly approximate it to a big sheet of aluminum or copper. What i also don't understand is how can the current be constantly induced with no movement. You see in the end of the video that the thing start heating up and the magnet drops down. I think that the thing heats up more quickly with the magnet over it, cause the induced current will dissipate power on the superconductor.

hi bro,

Current constantly running without any lost because it's a superconductor. Pretty much when you induce a current, it stays there forever as long as the material has superconductivity temperature.

Well lets think about this then...

The magnet has a field that is constant or as near to a constant. The super conducting material only has super conductivity when it is at the required temperature. I will assume that the material either conducts the lines very efficiently and the magnet holds itself up by the field lines or the material gets and induced mirror image of the lines as it is moving twords the material and holds on that way.

The ability to hold itself up is not a mystery. The magnets is the source at that point and the material is only channeling the lines or reflects the image back to the magnet and suspends the magnet.

The superconductivity is not actually absolute, theres still some resistance. Thats what i meant. We know that for inducing a current a magnet would need to move in relation to the electrons as to move them on the field, i think that under super conductive condition the electrons spin gain a kind of magnetic field that attracts and repels at the same time the magnet. Superconductors can held up to a certain amount of magnetic field, below this it will stop being superconductor.... I think is 20 tesla the limit

The electrons maybe by columbian repulsion by the size of the thing and the size of the field of the magnet, wants to go away but they need to stay there cause theres no way to go so they create this kind of trap field that hold the magnet. They are might be spinning. -

I think you're getting into it. You have two hypothesis. One is the magnet repel by the current, second is the induced mirror image that repels it.
