Show that coefficient of mutual induction for one coil due to current in the other coil always remains the same.

What will be the coefficient of mutual inductance of a pair of coil if a current of 3 ampere in one coil cause the flux in the second coil of 1000 turns to change by 10(-4) Wb in each turn ?

In an induction coil, the coefficient of mutual induction is 4 H. If a current of 5 A in primary coil is cut-off in 1/1500 s, the emf at the terminals of secondary coil will be

If the coefficient of mutual induction of primary and secondary of an induction coil is 6 henry and a current of 5 ampere is cut off in 2xx10^-4 s, ind the induced e.m.f. in the secondary coil.

The mutual inductance between two coils depends on

Explain self induction of a coil and give its unit.
