What is Magnetism and magnetic materials

Magnetism and magnetism are two different concepts. Magnetism refers to the property that a substance produces magnetization under the action of an external magnetic field. The magnet itself has magnetism, which is determined by its internal microstructure. When a magnet is placed in a magnetic field, the magnetic particles inside it will be arranged in a specific direction to form magnetization. Even if the external magnetic field is removed, the magnet still maintains its magnetized state because of the interaction between magnetic particles. Magnetic force is the force generated by the interaction of magnetic fields between magnetic substances. For example, like poles of two magnets repel each other and like poles attract each other. This force is the result of magnetic interaction between magnets. Therefore, magnetism describes the ability of substances to respond to magnetic fields, while magnetism describes the strength of interaction between magnetic substances.
