A Halbach array is a special arrangement of permanent magnets that strengthens the magnetic field on one side of the array while cancelling it to near zero on the other, achieved with a spatially rotating pattern of magnetisation. Its effect is roughly like many horseshoe magnets placed side by side with similar poles touching. The one-sided flux configuration was first described in 1957 by W. K. Westmijze and appears in a 1970 patent by James Winey of Magnepan; John C. Mallinson discovered the effect in 1973 and recognised its promise for magnetic tape technology. The physicist Klaus Halbach, at the Lawrence Berkeley National Laboratory during the 1980s, independently invented the array to focus particle accelerator beams.
