. 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

Answer:

Explanation:

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.

⇒emf=500(0.1)21

⇒emf=5.0V

Final Answer:

The correct option is (B).
