Substances respond weakly to magnetic fields with three other types of magnetism—paramagnetism, diamagnetism, and antiferromagnetism—but the forces are usually so weak that they can be detected only by sensitive instruments in a laboratory. We can also say that the diamagnetic substances get repelled by a magnet. See Wiktionary Terms of Use for details.
