. A coil having 500 square loops each of side 10 cm is placed

normal to a magnetic field which increases at the rate of 1 T s^-1 . The induced e.m.f. is

A: 0.1 V

B: 5.0 V

C: 0.5 V

D: 1.0 V


Best Answer



The emf induced in the coil can be given by 

emf=NAdB /dt  where N= number of coil turns,A is the area of the coil and dB /dt  is the rate of change of magnetic field.



Final Answer:

The correct option is (B).
