A magnet is plunged into and out of a coil of wire 2 times per second. This induces 5 volts.

a- 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?






b- 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?
