Yes. It's useful because when it's free to spin, it aligns itself with the Earth's magnetic field.

What does a compass does when it detects a magnet?

Why won't a compass work near a magnet?
The compass needle is itself a magnet which is why it always points north according to the earth's magnetic field. If you place a magnet (Whose magnetic power is stronger than the earth's) close to the compass its needle will be attracted t the magnet and not to the North Pole.
Infer what characteristic of a compass needle accounts for your observation of the compass and the magnet?
because the gravity of the earth
Is A compass needle permanent a magnet?
Compass needles are permanent magnets. in response to the Earth's magnetic field, the compass needle will point toward the geographic North Pole.
Why does a compass spin when it is placed next to a magnet?
A compass needle is a small magnet itself. When it is placed next to a larger magnet, the magnetic field of the larger magnet interacts with the magnetic field of the compass needle. This interaction causes the compass needle to align with the magnetic field of the larger magnet, causing it to spin and point in the direction of the magnetic field lines.
In what way is the earth a giant magnet?
In that it has a magnetic field - which can be detected by a compass needle.
How do you identify the north and south pole of a magnet?
