A current is induced in coil C_(1) due to the motion of current carring coil C_(2) as shown in Fig. 6.32. (a) Write any two ways by which a large deflection can be obtained in the galvanometer G. (b) Suggest an alternative device to demonstrate the induced current in place of a galvanometer. |

Answer» Solution :(a) Large deflection can be OBTAINED in the galvanometer G, if (i) the number of turns in coils `C_(1)` and `C_(2)` is increased. (ii) the coil `C_(2)` is moved at a faster rate, and (III) an iron rod is inserted into the coils along their AXIS. (b) We can use a low power indicator lamp to demonstrate the induced current in place of a galvanometer. |
