This is such a cool demonstration of induction and shows faradays law of induction.
The relationship between changing magnetic flux and induced electromotive force  (epsilon) is known as Faraday's law of electromagnetic induction:
The magnitude of an electromagnetic force induced in a circuit is proportional to the rate of change of the magnetic flux linkage that cuts across the circuit.
Induced voltage E is determined by two factors:
1) The amount of magnetic flux
2) The rate at which the magnetic field lines cut across the conductor
NB: The induced EMF acts as such to oppose the change that causes it (see details on previous) slide.

Makes you wonder if bird feathers are like this for this reason.

Cool I have seen the magnet in a copper tube but never the slotted axe. Thanks

I have an experiment for you: If you constructed a magnet just like these-- that have the same polarity-- such as a South to South (or north to north).. and you placed them really close together so that they are actively trying to repel from each other: what would happen then -- when you pass these discs through the center? There is still magnetic force there, it is just repelling rather than attracting-- so what happens then? Does it even interact with the steel plates at all? I've never seen this experiment done .. What happens if you put them very close together, so that the repel force is the strongest? Does it repel the discs too? or not interact at all??

1. It's not possible to have a North to North (south to south magnet 2. The Internet is free and you also got A.I to help you

@@Ripxy. Yes.. they repel.. that's the point. What effect would that have? I wonder

When transformers take advantage of both magnetic field vectors is when science isnt used against the populace
