Answer:
The correct option is c) half revolution
Explanation:
As we know that E.M.F is given by:
On every half-rotation, the direction of the induced current changes. As a result, the coil’s current stays in the same direction.
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
