Magnetism Experiments show that any substance can be magnetized to some degree in an external magnetic field, only the degree of magnetization differs. Based on the properties exhibited by substances in an external magnetic field, substances can be divided into five categories: paramagnetic substances, diamagnetic substances, ferromagnetic substances, ferrimagnetic substances, and antiferromagnetic substances.
