State the direction of the magnetic field inside the bar magnet.

Inside a solenoid,the magnetic field is constant in magnitude and direction.

State Faraday's laws of electromagnetic induction.

$A$ coil made of insulated copper wire is connected to a galvanometer. What will happen to the deflection of the galvanometer if this coil is moved towards a stationary bar magnet and then moved away from it? Give reason for your answer and name the phenomenon involved.

Meena draws magnetic field lines of a field close to the axis of a current-carrying circular loop. As she moves away from the centre of the circular loop,she observes that the lines keep on diverging. How will you explain her observation?

List two methods of producing magnetic fields.
