A copper ring is held horizontally and a bar magnet is dropped through the ring with its length along the axis of the ring. Will the acceleration of the falling magnet be equal to, greater than or less than that due to gravity? 

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 $I$ 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 $\left(1\right)$ and $\left(2\right)$ 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 $\mathrm{v}$?

The figure shows two identical rectangular loops $\left(1\right)$ and $\left(2\right)$ placed on a table along with a straight long current carrying conductor between them. Will the emf induced in the two loops be equal? Justify your answer.

In the figure, a bar magnet falling under gravity through an air-cored coil C. Plot a graph showing the variation of induced emf$\left(\mathrm{E}\right)$ with time $\left(\mathrm{t}\right)$ What does the area enclosed by the $\mathrm{E}-\mathrm{t}$ curve depict?
