Question

a larger circular coil of radius R and a small circular coil of
radius r are put in vicinity of each other if the cofficient of
mutual induction of this pair equals 1mH , what would be the flux
linked with the larger coil , when a current of 0 5 A flow through
the smaller coil ?

Ï† = 1 mH = 1 = 1x10-3 H
I = 0 5 A
As we know ,
Ï† = MxI
1x10-3 = Mx0 5
M = 2x10-3 weber/ampere
If the current through the small coil falls to zero then the
induced current in the larger coil becomes zero
