Electricity may be generated by rotating a loop of wire between the poles of a magnet.The induced current is greatest when
A)the plane of the loop is parallel to the magnetic field.
B)the plane of the loop is perpendicular to the magnetic field.
C)the magnetic flux through the loop is a maximum.
D)the plane of the loop makes an angle of 45° with the magnetic field.

Question

Quizplus · Accepted Answer

The induced current is greatest when the rate of change of magnetic flux is greatest, which occurs when the plane of the loop is parallel to the magnetic field, as this is when the loop cuts through the maximum number of magnetic field lines per unit time.
