Why does a compass needle get deflected when brought near a bar magnet?
Share
Magnetic compass needle and bar magnet both have magnetic field. When they brought near to each other, these magnetic fields interact each other giving deflection in needle.

Compass needle is a bar magnet when it is brought near a bar magnet, its magnetic field interacts with the magnetic field line of the bar magnet. Therefore deflection occurs in the compass needle.
When a compass needle is brought near a bar magnet, the compass needle experiences a deflection. This happens because of interaction of magnetic fields of the compass needle and the bar magnet.
The needle of a compass 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.
The compass needle is a small bar magnet. When a compass needle is brought near a bar magnet than due to repulsive force between like poles and attraction between unlike poles, the compass needle is deflected. Finally, the compass needle comes to rest in the direction of net magnetic field.
