Important Questions on Electromagnetic Induction




Two identical circular coils A and B are placed parallel to each other with their centres on the same axis. The coil B carries a current in the clockwise direction as seen from A. What would be the direction of induced current in A as seen from B when the coil B is moved towards A, keeping the current in B constant?


A bar magnet is pulled rapidly through a conducting loop along its axis with a uniform velocity with its south pole entering the loop first. Sketch qualitatively the joule heating as a function of time (Take the induced current positive if it is clockwise when viewed along the path of the magnet).

The figure given below shows two identical rectangular loops and placed on a table along with a straight long current carrying conductor between them. What will be the directions of the induced currents in the loops when they are pulled away from the conductor, with some velocity ?
