प्रश्न
Predict the direction of induced current in the situation described by the following figure.
उत्तर
Lenz's law specifies the direction of the induced current in a closed loop. Using Lenz’s rule, the direction of the induced current in the given situation can be predicted as follows:
The induced current in the right coil drives X to Y.
The direction of the induced current is along the xryx.

A coil is suspended in a uniform magnetic field, with the plane of the coil parallel to the magnetic lines of force. When a current is passed through the coil it starts oscillating: It is very difficult to stop. But if an aluminium plate is placed near to the coil, it stops. This is due to:
