Final answer:

A bar magnet is a permanent magnet with two poles that create a magnetic field. It does not need an electric current to exhibit magnetic properties. The magnetic field of a bar magnet can be observed using a compass needle.


Explanation:

A bar magnet is a permanent magnet that has two poles, a north pole, and a south pole. These poles create a magnetic field around the magnet.

Unlike an electromagnet, a bar magnet does not require an electric current to be present to exhibit magnetic properties. It remains magnetized and has a magnetic field as long as it is not demagnetized.

When a compass needle is placed near a bar magnet, it aligns itself along the magnetic field lines, indicating the direction of the magnetic field of the bar magnet.
