Magnetic monopoles In 1931, Dirac proposed that the existence of a single magnetic monopole in the universe would suffice to explain the quantisation of electrical charge. No such monopole has been detected, despite numerous attempts and preliminary claims. (see also Searches for magnetic monopoles).
