A coil having an area of `3m^(2)` is placed in a magnetic field which changes from a `9 Wb//m^(2)` to `5Wb//m^(2)` in three seconds. The e.m.f. Induced in the coil is

A

3V

B

4V

C

5V

D

1V

Text Solution

Verified by Experts

The correct Answer is:
B
`e = A((B_(2)-B_(1))/(t)) = (3 xx 4)/3 = 4 V`.
