One of the mysteries of the English language finally explained.
A single electric charge or magnetic pole, especially a hypothetical isolated magnetic pole.
- ‘Pinfold and his team are searching for an elusive, almost mythical, particle called a magnetic monopole.’
- ‘‘In a sense the searches for both magnetic monopoles and gravity waves are very similar,’ he says.’
- ‘The coupling of electrons to these momentum-space monopoles is mathematically similar to their coupling to the real-space magnetic monopoles that have long been sought by particle physicists.’
- ‘The result would be quite different if the magnetic dipoles were composed instead of free monopoles, analogous to electric charges.’
- ‘Yet particle theories like Grand Unified Theories and superstring theory predict magnetic monopoles should exist.’
2A radio antenna or pylon consisting of a single pole or rod.
- ‘If we can't do that, we would need to have a 15 metre monopole somewhere in the vicinity, and that would have more visual effect.’
- ‘Marsis features three long antenna booms - a dipole and monopole - that broadcast very long wavelength radio waves toward the planet.’
- ‘A digital radio hi-fi tuner will come with an indoor aerial, either a ribbon dipole or a monopole (half dipole).’
- ‘Common HF antennas like vertical monopoles, horizontal wire dipoles, and loop antennas all provide omni-directional communications when configured properly.’
- ‘He said that most households would need to re-orient their TV antennas from the existing northerly direction to point to the new monopole.’

Late 19th century: from French, ‘monopoly’.
