All magnets are permanent magnets.
True
False
False.
There are two main types of magnets: permanent magnets and electromagnets. Permanent magnets are made from materials that are magnetized and retain their magnetism. Electromagnets are made by wrapping a wire around a ferromagnetic core and passing an electric current through the wire, creating a magnetic field. Electromagnets can be turned on and off, while permanent magnets cannot.
Therefore, not all magnets are permanent magnets.
