What is the reason (or responsible) for the generation of current in the coil when a bar magnet rotates in it?

What happens do the rotation of the coil if the direction of current in the coil remains unchanged?

What will happens if the direction of current through the coil (which is placed in a magnetic field) is reversed every half rotation?

The north of a bar magnet is moved towards a coil along the axis passing through the centre of the coil and perpendicular to the plane of the coil. The direction of the induced current in the coil when viewed in the direction of the motion of the magnet is

The north of a bar magnet is moved towards a coil along the axis passing through the centre of the coil and perpendicular to the plane of the coil. The direction of the induced current in the coil when viewed in the direction of the motion of the magnet is

A coil is hung as shown in the figure.A bar magnet with north pole facing the coil is moved perpendicularly State the direction of the flow of the current induced as the coil,keeping the direction of bar magnet In views.

A cylindrical bar magnet is kept along the axis of a circular coil. Will there be a current induced in the coil if the magnet is rotated about its axis? Give reasons.

An a.c. generator consists of a coil of 50 turns and area 2.5 m^(2) rotating at an angluar speed of 60 rad s^(-1) , in a uniform magnetic field B = 0.30 T between two fixed pole pieces. The resistance of the circuit including that of coil is 500 Omega . (a) What is the max. current drawn form the generator? (b) What is the flux through the coil when the current is zero ? What is the flux when the current is max. ? (c ) Would the generator work if the coil were statinary and instead pole pieces rotated together with the same speed as above ?
