Correct Answer:
C. The compass needle is a small bar magnet.
Explanation:
The correct answer is Option C: The compass needle is a small bar magnet.
A compass needle is essentially a tiny, pivoted magnet with its own north and south poles. When it is positioned near a bar magnet, the magnetic fields of the two objects interact. According to the laws of magnetism, like poles repel and opposite poles attract. This magnetic force exerts a torque on the compass needle, causing it to rotate and align itself with the magnetic field lines of the bar magnet. This explains why the needle moves or deflects from its original position when a magnetic source is introduced nearby.
