Assertion : When a bar magnet is freely ...

Assertion : When a bar magnet is freely suspended, it points in the north-south direction.
Reason : The earth behaves as a magnet with the magnetic field pointing approximately from the geographic south to north.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true and reason is not the correct explanation of assertion.

C

If assertion is ture but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:

  • Which of the following statements is/are correct about magnetism? I The earth behaves as a magnet with the magnetic field pointing approximately from the geographic South to the North. II. When a bar magnet is freely suspended, it points in the North-South direction. The tip which points to the geographic North is called the North-pole and the tip which points to geographic South is called the South-pole of magnet. III. There is a repulsive force when North-poles (or South-poles) of two magnets are brought close one magnet and. the South-pole of other. IV. We can isolate the North or South-pole of a magnet.
