In Fig. a coil B is connected to a low voltage bulb L and placed parallel to another coil A, as shown. Explain the following observations : (i) bulb lights (ii) gets dimmer if the coil B is moved upwards.

A coil Q is connected to low voltage bulb B and placed near another coil P as showns in Fig. Give reasons to explain the following observation : (a) The bulb B lights (b) Bulb gets dimmer if coil Q is moved toward left.

A coil Q is connected to low voltage bulb B and placed near another coil P as shown in the fiugre. Give reasons to explain the following observations : (a) The bulb 'B' lights. (ii) Bulb gets diameter if the coil Q is moved towards left.

A coil Q is connected to low voltage bulb B and placed near another coil P as shown in the fiugre. Give reasons to explain the following observations : (a) The bulb 'B' lights. (ii) Bulb gets diameter if the coil Q is moved towards left.

Coil A is connected to an ac source through a switch S. Coil B, kept close to A, is connected to a low voltage bulb (L). Explain the following observations. (i) When S is closed, the bulb lights up. (ii) With S closed if B is moved away from A, the bulb gets dimmer. (iii) With S closed, if a copper plate C is inserted between the coils, the bulb gets dimmer.

There are two coils A and B as shown in Fig.

There are two coils A and B as shown in Fig.

The identical coils A,B and C are placed with their planes parallel to one another. Coil A and coil C carry the electric current as shown in Fig. SAQ 15 coil B and C are fixed. Coil A is moved towards B with a constant speed. Is their any induced current in B?

Three indentical closed coils A,B and C are placed with their planes parallel to one another. Coils A and C carry equal currents as shown in fig. Coils B and C are fixed in position and coil A is moved towards B with uniform motion. Is there any indenced current in B? If no, give reasons. If yes mark the direction of the induced current in he diagram.
