Elecromagnetic Inducton: Faraday's laws.
Not what you're looking for?
A magnet is plunged into and out of a coil of wire 2 times per second. Thus induces 5 volts. If the rate of motion changes so that the magnet is plunged in and out 6 times per second, what will be the new induced voltage?
If the number of coils in the wire is doubled from 100 to 200, and the original rate of 2 times per second is kept the same, what will be the new voltage induced?

Solution Summary
Two small conceptual questions to understand rate of change of magnetic flux and induced EMF.
Solution Preview
According to Faraday's law of electromagnetic induction, the induced EMF in a closed loop or coil is directly proportional to the rate of change of flux through it.
Here in the first case as the number of times the the magnet is plunged six times in ...
