Question
What is the direction of induced currents in metal rings 1 and 2 when current I in the wire is increasing steadily?
Solution
Using Lenz's Law we can predict the direction of induced current in both the rings. Induced current opposes the cause of increasing of magnetic flux.
So, induced current will be clockwise in ring 1 and anticlockwise in ring 2.

Lenz's law gives ______
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:
