The magnet in a compass is a permanent magnet. It retains its magnetism without the need for an external electrical current.
It is a permanent magnet. Electromagnets(as the name suggests) requires an electric source to become a magnet, when the power source is turned off it will not function as a magnet.

Usually it's a permanent magnet. You could use an electromagnet instead, but doing so is considerably harder from an engineering standpoint.
No, an electromagnet is not a permanent magnet. It is a magnet that produces a magnetic field when an electric current is passed through it, and the magnetic field disappears when the current is turned off.
The reason is because an electromagnet is hooked up to an artificial energy force, while a magnet is a charged piece of metal example: a battery hooked up to a piece of iron attracts paperclips but a magnet can be made by stroking a paperclip against a bar magnet to create a temporary magnet somewhat how a compass works
PermanentThere is no source of current in a compass, therefore the magnet is a permanent magnet.

An electromagnet is a stronger magnet.
An electromagnet is a temporary magnet that only produces a magnetic field when an electric current is flowing through it, while a permanent magnet retains its magnetism without needing an external electric current. Additionally, the strength of an electromagnet can be easily adjusted by changing the amount of current flowing through it, while the strength of a permanent magnet is fixed.
