Question

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

Answer 1

Answer:

Bar magnet

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.

Answer 2

Explanation:

• 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.

• A current carrying conductor produces a magnetic field around it.
• This magnetic field apply force on the magnetic needle of compass, and thus the needle shows deflection.
