Magnet is a material or object that produces a magnetic field, which exerts a force on ferromagnetic materials like iron, nickel, and cobalt, and can attract or repel other magnets. The magnetic field is caused by the alignment of atomic magnetic moments, typically from electron spin.
Types of magnets:
Temporary magnets: Exhibit magnetism only when influenced by an external magnetic field
Common applications include:
Magnetic separators and lifting equipment
Magnet performance is often characterized by properties such as remanence, coercivity, and maximum energy product (BHmax).
