Question

why does a compass needle get deflected when brought near a bar magnet​

Answer 1

Answer:

A compass needle gets deflected when brought near a bar magnet because a magnetic compass can be considered as a pole, and the magnet creates a field. If we place the two at rest, then the compass will be reflected in a direction, and it will be constant.

Answer 2

Answer:

The compass needle is a small magnet. That’s why when a compass needle is brought near a bar magnet, its magnetic field lines interact with that of the bar magnet. Hence, a compass needle gets deflected near the magnet bar.
