The current in a coil of inductance $0.2 \,H$ changes from $5A$ to $2A$ in $0.5\,sec$. The magnitude of the average induced emf in the coil is

The induction coil works on the principle of

At the mid point along the length of a long solenoid, the magnetic field is equal to x. If the length of the solenoid is doubled and the current is reduced to half, the field at the new mid point will be nearest to
