Magnets with a single pole are still giving physicists the slip

Experiments are teasing out new details about the unique properties of ‘magnetic monopoles’

SOLE POLE  Scientists are searching for hypothetical particles called magnetic monopoles, which have a single north or south magnetic pole. Such particles might be created in pairs (red in the lower right corner and blue in the upper left corner, illustrated above) in collisions of proton beams (white) at accelerators like the Large Hadron Collider.
