A bar magnet is quickly moved towards a conducting loop having a capacitor as shown.

Predict the polarity of the plates A and B of the capacitor.

Text Solution

Verified by Experts

According to Lenz law, induced current will flow in the coil in anticlockwise direction (when looked from the side of the magnet) i.e. from plate A to the plate B of the capacitor. Hence, plate A will be positive and plate B will be negative.
