magnetic monopole | has definition A hypothetical particle that carries an isolated north or south magnetic pole. This is in contrast to magnets which are north-south pole pairs. If magnetic monopoles exist, they must be very massive. | ![has source: Coughlan, G.D., Dodd, J.E. 1999 The Ideas of Particle Physics, Cambridge University Press, 2001-09-27 09:28:16.0 has source: Coughlan, G.D., Dodd, J.E. 1999 The Ideas of Particle Physics, Cambridge University Press, 2001-09-27 09:28:16.0](facet.gif) |
has definition a massive particle with but one magnetic pole, the production of which is indicated in some theories of the early universe. | ![has source: Ferris, T. 1988 Coming of Age in the Milky Way, Morrow, 2001-09-27 09:28:16.0 has source: Ferris, T. 1988 Coming of Age in the Milky Way, Morrow, 2001-09-27 09:28:16.0](facet.gif) |
has definition A magnet with an isolated north (or south) pole, rather than a pair of equal-strength north and south poles, as in conventional magnets. Magnetic monopoles have never been observed, but they are predicted to exist by grand unified theories. | ![has source: Guth, A.H. 1997 The Inflationary Universe, Addison-Wesley, 2001-09-27 09:28:16.0 has source: Guth, A.H. 1997 The Inflationary Universe, Addison-Wesley, 2001-09-27 09:28:16.0](facet.gif) |
has definition An hypothesized particle that would have either a magnetic north pole or a magnetic south pole but not both. all magnetic particles and magnets ever observed have both poles. Magnetic monopoles are predicted by grand unified theories of physics. that grand unified theories predict the existence of large numbers of magnetic monopoles, when none have been discovered, is called the monopole problem. (see grand unified theories.) | ![has source: Lightman, A., Brawer, R. 1990 The Lives and Worlds of Modern Cosmologists, Harvard University Press, 2001-09-27 09:28:16.0 has source: Lightman, A., Brawer, R. 1990 The Lives and Worlds of Modern Cosmologists, Harvard University Press, 2001-09-27 09:28:16.0](facet.gif) |
has definition has definition A hypothetical quantum object being a single, isolated magnetic pole. Normally, magnetic poles, the sources of a magnetic field, occur in pairs as north and south poles. | ![2001-09-27 09:28:16.0 2001-09-27 09:28:16.0](facet.gif) |
