. 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).
