| 单词 | magnetic monopole |
| 释义 | magnetic monopole 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 mass of order 10 16 GeV). Magnetic monopoles are also predicted to exist in Kaluza-Klein theories and superstring theory |
