magnetic monopole

Physics

A hypothetical magnetic entity consisting of an isolated elementary north or south pole. It has been postulated as a source of a magnetic field by analogy with the way in which an electrically charged particle produces an electric field. Numerous ingenious experiments have been designed to detect the monopole, but so far none has produced an unequivocal result. Magnetic monopoles are predicted to exist in certain gauge theories with Higgs bosons. In particular, some grand unified theories predict very heavy monopoles (with a mass of order 10¹⁶ GeV). Magnetic monopoles are also predicted to exist in Kaluza–Klein theories and superstring theory. Magnetic monopoles feature prominently in many attempts to describe quark confinement and the concept of duality in gauge theories.

Astronomy

A hypothetical point-like defect in the fabric of spacetime, produced in some models of the early Universe. They are so named because they would behave like the isolated north or south pole of a magnet. A magnetic monopole is the one-dimensional analogue of the cosmic string, domain wall, and cosmic texture. Monopoles, as well as the other types of defect, are a consequence of some forms of grand unified theory (GUT). No monopoles have yet been detected.

Electronics and Electrical Engineering

A hypothetical magnetic particle with a single magnetic charge of either north or south. Such a particle would be analogous to the electrical particles the electron and proton. Maxwell’s equations would prove completely symmetrical if the existence of such particles were to be proved. Magnetic monopoles were postulated on conservation and symmetry principles and are thought to be more massive than nucleons. Their existence is not barred by quantum theory nor classical electromagnetic theory and it has been suggested that they occur in extremely high energy cosmic rays. No proof of their existence or otherwise has yet been found despite intensive searches for them.
