How does the mutual inductacne of a pair of coils get affected when
a tahin iron sheet is placed between the two coils, other factors remaining the same?

How does the mutual inductacne of a pair of coils get affected when distance between coils is increased? Explain your answer in each case?

How does the mutual inductacne of a pair of coils get affected when the number of turns in each coil is decreased? Explain your answer in each case?

How does the self inductance of an air coil change, when an iron rod is introduced in the coil?

A coil A is connected to a voltmeter V and the other coil B to an alternating current source. If a large copper sheet C is placed between the two coils, how does the induced e.m.f. in the coil A change due to current in coil B?

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

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

How is the graitational force between two point masses affected when they are dipped in waterkeeping the separation between them the same?

Two coils are placed closed to each other. The mutual inductance of the pair of coils depends upon

The mutual inductance between thetwo coils is maximum, when one coil is wound over the other. (True/False)
