Using Lenz's law, predict the direction ...

Using Lenz's law, predict the direction of induced current in conducting rings 1 and 2 when current in the wire is steadily decreasing.

Text Solution

Verified by Experts

According to Lenz.s law, a current will be induced in the coil which will produce a flux in the opposite direaction. If the current decreases in the wire, the induced current flows in ring 1 in clockwise direaction, the induced current flows in ring 2 in anti - clockwise direaction.
