Question

Why does a compas needle get deflected when brought near a bar magnet ​

Answer 1

Answer:

The Compass needle gets deflected, because the bar magnet is the nearest magnet around the magnetic compass. It also deflects because the compass needle has lower magnetic force when compared to the bar magnet. Usually the needle turns towards the north, but when the bar magnet is near to the needle, the magnetic fields of both of these objects get distracted.

Answer 2

$\bigstar\sf\purple{Answer}\bigstar$

The compass needle is a small magnet. When the compass needle is brought close to a bar magnet, the magnetic field lines of the compass needle interact with the magnetic field lines of bar magnet, which causes the compass needle to deflect.
