Mark the direction of current through the galvanometer, and the magnetic poles induced at the ends of the coil. Use lenz’s law. (The winding is clockwise).

Predict the polarity of the capacitor $\mathrm{PQ}$ in the situation shown.

In the adjoining Fig. $\left(a\right)$ and $\left(b\right)$, a current-carrying solenoid is being taken towards a conducting-loop. What shall be the direction of the induced current in the loop as observed by an observer on the other side?

            $\left(a\right)$

In the adjoining Fig. (a) and (b), a current-carrying solenoid is being taken towards a conducting-loop. What shall be the direction of the induced current in the loop as observed by an observer on the other side?

A copper ring is suspended by a thread. One end of a magnet is brought horizontally towards the ring. How will it affect the position of the ring?

A bar-magnet falls down through a coil. Will the acceleration of the magnet equal to 'g'?
