WebMagnets that can maintain their magnetism for a long time are called permanent magnets, such as natural magnets (magnetite) and artificial magnets ( aluminum – nickel – cobalt alloy), etc. Permanent magnets are not easily demagnetized or magnetized and the polarity of them will not change. However, if the permanent magnet is heated above ...
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.
