A magnet is quickly moved in the direction indicated by an arrow between two coils C_(1) and C_(2) as shown in the Fig. 6.34. What will be the direction of induced current in each coil as seen from the magnet ? Justify you answer. |

Answer» Solution :In the figure, the magrant NS, with its N-pole facing coil `C_(1)`, is moving away from the coil `C_(1)`. Hence, in accordance with Lenz.s law the INDUCED current will flow in clockwise DIRECTION when seen from the magnet. In such a situation face of coil `C_(1)` facing N-pole of magnet will DEVELOP S POLARITY and will oppose the motion of magnet away from the coil `C_(1)`. Again the magnet NS, with its S-pole facing coil `C_(2)`, is moving towards the coil `C_(2)`. Hence in accordance with Lenz.s law, the induced current will flow in clockwise direction when seen from me magnet. In such a situation, face of coil `C_(2)` facing S-pole of magnet will develop a Spolarity and will oppose the motion of magnet towards the coil `C_(2).` |
