Question

(3) X and Y coils are joined in a circuit in such a way that
when the change of current in X in 2A, the change in the
magnetic flux in Y is 0.4 Wb. The mutual induction of the
system of two coils is ........ H.​

Answer 2

Answer:

We know that, the magnetic flux associated with coil Y is directly proportional to current flowing in X coil.

ϕy∝lx

Here, ϕy= Change in magnetic flux in coil Y

lx= change in current in coil X

M= mutul incductance

We have ϕy=0.4Wb

0.4=M×4

=40.4=0.1H
