Accurately computed magnetic field and scalar potential of an infinite array of tilted bar magnets. Such configuration is often used in magnet motor perpetual motion machine designs with the intention to produce a continuous field along the transversal direction. Contrary to naive imagination, the field doesn't emerge along the magnet axes, but perpendicular to the whole array. The potential is periodic in transversal direction, so that no work can be done by moving magnetic poles along the array.
