A coil having `500` square loops each of side `10 cm` is placed normal to a magnetic flux which increase at the rate of `1.0 "tesla"/"second"`. The induced r.m.f. in volts is

A

0.1 V

B

0.5 V

C

1V

D

5V

Text Solution

Verified by Experts

The correct Answer is:
D
Here , area A `= 500 (10//100)^2 = 5m^2`
`(dB)/(dt) = 1Ts^(-1)`
Induced emf `|epsi| = (dphi)/(dt) = A (dB)/(dt) = 5 xx 1 = 5`volt
