There are two coils A and B separated by some distance. If a current of 2 A flows through A, a magnetic flux of Wb passes through B (no current through B). If no current passes through A and a current of 1A passes through B, what is the flux through A ?
The mutual inductance of coil B with respect to coil A is
According to the problem, total flux
Hence, the Mutual inductance
As we know that mutual inductance is same for both the coils with respect to each other. So,
And let is the total flux through A if no current passes through A.
