n52 magnet Heilbeck magnets array
Heilbeck magnets array is a magnet structure, in 1979 the American scholar Klaus Halbach to do electron acceleration experiments discovered this special permanent magnet structure and gradually improved, and finally formed the so-called "Halbach" magnets, it is the engineering of the approximate ideal structure, which uses a special arrangement of the magnet unit to enhance the field strength per unit direction, the goal is to use the smallest number of magnets to produce the strongest magnetic field.
