Answer:

permanent magnets, temporary magnets, and electromagnets

Explanation:

Permanent magnets are types of magnets that maintain magnetism for a very long time.

Temporary magnets are the opposite of permanent magnets, they will have magnetism for a short amount of time.

Electromagnets works when electric currents coils around a metal which creates their artificial magnetic fields, creating magnetism

Answer:

6) permanent magnets

7) temporary magnets

8) electromagnets

Explanation:

Magnets can be made by placing a magnetic material, such as iron or steel, in a strong magnetic field. Permanent, temporary, and electromagnets can be produced in this manner

Permanent magnets emit a magnetic field without the need for any external source of magnetism or electrical power.

Temporary magnets behave as magnets while attached to or close to something that emits a magnetic field, but lose this characteristic when the source of the magnetic field is removed.

Electro-magnets require electricity in order to behave as a magnet. Electromagnets are used when very strong magnets are required.
