A rectangular coil of copper wire is rotated in a magnetic field. The direction of induced current changes once in each:
(a) two revolutions
(b) one revolution
(c) half revolution
(d) one-fourth revolution

Solution
(c) half revolution
If a rectangular coil of copper wire is rotated in a magnetic field, the direction of magnetic field to the given side of coil changes after half revolution and the direction of induced current also changes simultaneously.
