Question

Define mutual flux? Explain its significance

Answer 1

flux is just the magnetic lines and the magnetic lines present in between two magnets or solenoid is mutual flux. These are the lines through which the attraction and repulsion occurs

Answer 2

Mutual inductance is where the magnetic flux of two or more inductors are “linked” so that voltage is induced in one coil proportional to the rate-of-change of current in another. A transformer is a device made of two or more inductors, one of which is powered by AC, inducing an AC voltage across the second inductor.
