Historical background Early science and classical physics Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles. Magnetism in bar magnets and electromagnets is not caused by magnetic monopoles, and indeed, there is no known experimental or observational evidence that magnetic monopoles exist. The known elementary particles that have electric charge are electric monopoles. Modern interest in the concept stems from particle theories, notably the grand unified and superstring theories, which predict their existence. A magnetic monopole would have a net north or south "magnetic charge". In particle physics, a magnetic monopole is a hypothetical elementary particle that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). A magnetic monopole cannot be created from normal matter such as atoms and electrons, but would instead be a new elementary particle. Instead, each piece has its own north and south poles. If a bar magnet is cut in half, it is not the case that one half has the north pole and the other half has the south pole. It is impossible to make magnetic monopoles from a bar magnet.
