Solution

The correct option is B Greater in first case.
Whenever there is a change in magnetic field linked with a coil, an e.m.f. is induced in the coil. The magnitude of this induced e.m.f. is directly proportional to the rate of change of magnetic flux. So, it will be greater in the first case as the rate of change of magnetic flux is higher as compared to the second case.
