Magnetic monopoles detected in a real magnet for the first time
This is an impression of a "spin spaghetti" of Dirac strings. Credit: HZB / D.J.P. Morris & A. Tennant Magnetic monopoles are hypothetical particles proposed by physicists that carry a single magnetic pole, either a magnetic North pole or South pole. In the material world this is quite exceptional because magnetic particles are usually observed as dipoles, north and south combined.
