A bar magnet is falling through a loop of wire with constant velocity.The north pole enters first.The induced current will be greatest in magnitude when the magnet is located so that
A)the loop is near either the north or the south pole.
B)the loop is near the north pole only.
C)the loop is near the middle of the magnet.
D)with no acceleration,the induced current is zero.

Question

Quizplus · Accepted Answer

The induced current is greatest when the rate of change of magnetic flux through the loop is greatest, which occurs when the loop is near either the north or the south pole of the magnet.
