A permanent magnet passes through a loop of wire. When is the electrical potential difference in the loop the GREATEST? a
When the permanent magnet is held far away from the loop of wire.
b
When the permanent magnet is passed slowly through the loop of wire.
When the permanent magnet is passed quickly through the loop of wire.
с
d
When the permanent magnet is held still in the middle of the loop of wire.
