Question

What is a magnet? Name the two types of magnets.​

Answer 1

A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.

Magnets are categorized by their source of magnetism.

• Temporary magnets become magnetized in the presence of a magnetic field.

• Permanent magnets do not easily lose their magnetism.

• Electromagnets are created by running an electrical current through a coil with a metal core.

Answer 2

Answer:

Permanent magnets are magnets that retain their magnetism once magnetized. Temporary magnets are materials magnets that perform like permanent magnets when in the presence of a magnetic field, but lose magnetism when not in a magnetic field.
