Faradays Law - Back EMF Eddy Currents Video 2 - AQA A Level Physics

Описание к видео Faradays Law - Back EMF Eddy Currents Video 2 - AQA A Level Physics

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.
