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`

B

`0.5`

C

1

D

5

Text Solution

Verified by Experts

The correct Answer is:
D
Induced emf, `e=-N(dphi)/(dt)`
`|e|=N(dphi)/(dt)=N(d)/(dt)(BA costheta)=N(dB)/(Dt).A costheta`
`=500xx1xx(10xx10^(-2))^(2)cos 0^(@)`
`=5V`
