Why the magnet suspended freely, aligns itself in the north-south direction of the Earth?

Text Solution

Verified by Experts

The magnet suspeded freely aligns itself in the north-south direction of the Earth because the Earths acts like a huge magnet with its magnetic force at south heading towards its geometric north and its magnet north heading towards geometric south.

    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.
