Two coils are at fixed locations. When coil 1 has no current and the current in coil 2 increases at the rate of 15.0A/s the emf in coil 1 in 25.0mV, when coil has no current and coil 1 has acurrent of 3.6A, the flux linkage in coil 2 is

A

`16 m Wb`

B

`10 m Wb`

C

`4.00 m Wb`

D

`6.00 mWb`

Text Solution

Verified by Experts

The correct Answer is:
D
Coefficent of mutual inductance `M` is given by
`|M| = (e_(i))/((di_(2)//dt)) = (phi_(2))/(i_(1))`
`= 6 xx 10^(-3) = 6 mWb`
