question_answer

The north pole of a magnet is brought near a metallic ring. The direction of the induced current in the ring will be

A) towards south

B)        towards north  

C) anti-clockwise    

D)        clockwise.

Correct Answer: C

Solution :

                When the north pole of a magent is brought near a metallic ring, the induced current produced in the ring will be such that it opposes the growth of current in the ring. Thats why by Lenzs law, there must be a magnetic north pole created in the ring so that it can repel the approaching north pole. Now the direction of the current will be clockwise if we view it from behind the ring and it will be anticlockwise if we view it from above.
