Question

Ganeshan set up an experiment using two bar magnets one of which is marked N (North pole) and S (South pole) as shown in the figure. He noticed that the upper magnet is lifted up in air.

Identify X and Y poles of the upper magnet.

• A. X is the north pole, Y is the south pole.
• B. X is the south pole, Y is the north pole.
• C. Both X and Y are north poles.
• D. Both X and Y are south poles.

Answer 1

The correct option is A X is the north pole, Y is the south pole.

Like poles of magnets repel and unlike poles attract.
The upper magnet is lifted up in air. Therefore, it is being repelled by the bottom magnet. Hence, it can be concluded that X is the north pole and Y is the south pole in the upper magnet.
