Will there be any current induced in the coil shown in Fig if a bar magnet is swiftly moved towards or away from the coil. If yes, what will be the direction of current?

 

Predict the polarity of the plate $A$ of the capacitor, when a magnet is moved towards it, as shown in Fig.

As shown in Fig. a conducting rod $AB$ moves parallel to X-axis in an uniform magnetic field, pointing in three positive Z-direction. The end $A$ of the rod gets positively charged. Is this statement true? Give reason.

Fig. shows a horizontal solenoid connected to a battery and a switch. A copper ring is placed on a frictionless track, the axis of the ring being along the axis of the solenoid. What happens to the ring, as the switch is closed?

If the resistance of the circuit shown in Fig.(a) be decreased, what will be the direction of current induced in the circuit shown in Fig.(b)?

What is the magnitude of the induced current in the circular loop $KLMN$, of radius '$r$' if the straight wire $PQ$ carries a steady current of magnitude '$i$' ampere?

Fig. shows two positions of a loop $PQR$ in a perpendicular uniform magnetic field. In which position of the coil is there an induced emf?

In the given figure, $A$ and $B$ are identical magnets. Magnet $A$ is moved away from the coil with a given speed. Magnet $B$ is moved towards the coil with the same speed. What is the induced emf in the coil?

A bar magnet is moved in the direction indicated by an arrow between two coils $AB$ and $CD$ as shown in the figure. Indicate the direction of the induced current in each coil.
