Define mutual inductance and write its S.I. units

Define the term 'mutual inductance' between the two coils.

#### Solution 1

Mutual inductance is the property of two coils by the virtue of which each opposes any change in the value of current flowing through the other by developing an induced *emf*.

The SI unit of mutual inductance is henry and its symbol is H.

#### Solution 2

The ratio of magnetic flux passing through one coil to the current passing through the other is known as mutual inductance between the two coils.
