Question

In the given figure the north pole of a magnet is brought towards a closed loop containing a condenser
hen positive charge will be produced on
[ ]
a) Plate A
b) Plate B
c) Neither on plate A nor on plate B

d) Either on plate A or on plate B
​

Answer 1

A positive charge will be produced on Plate A.

Explanation:

• A magnet has north and south pole, when the north pole is approaching an object then a current will be induced in the loop.
• The direction of current produced will be clockwise i.e from a positive terminal to the negative terminal in the loop.
• Thus the charge produced on plate A will be positive and that on plate B will be negative.
