Which factors should be modified to change the amount of current induced in the wire?

Question

A) the dimensions of the coils and the length of the rotating shaft
B) the dimensions of the slip rings and the distance from the source of the rotation
C) the number of loops in the coil and the distance from the source of the rotation
D) the number of loops in the coil and the strength of the permanent magnet

Answer 1

C) the number of loops in the coil and the distance from the source of the rotation

By increasing the number of loops in the coil, the amount of current induced in the wire will increase. Additionally, adjusting the distance from the source of the rotation will also affect the amount of current induced in the wire.
