A square non-conducting loop, on a side, is placed in a magnetic field. The centre of side coincides with the centre of magnetic field. The magnetic field is increasing at the rate of . The potential difference between and is:




Important Questions on Electromagnetic Induction
A metallic ring is attached with the wall of a room. When the north pole of a magnet is brought near to it, the induced current in the ring will be

A copper ring is held horizontally and a bar magnet is dropped through the ring with its length along the axis of the ring. The acceleration of the falling magnet while it is passing through the ring is

A copper ring, as shown in the figure, is held horizontally and a bar magnet is dropped through the ring with its length along the axis of the ring. The acceleration of the falling magnet, while it is passing through the ring is




The current flowing in two coaxial coils is in the same direction. On increasing the distance between the two, the electric current will

A metallic ring, connected to a rod, oscillates freely like a pendulum. If now a magnetic field is applied in horizontal direction, so that the pendulum now swings through the field, the pendulum will

A current carrying solenoid is approaching a conducting loop as shown in the figure. The direction of induced current as observed by an observer on the other side of the loop will be
