Abstract
An arrangement and method orients the magnetization direction of magnetic layers on a plate shaped substrate on a mounting. The mounting defines a positioning plane for the substrate and a magnet arrangement is on one side of the positioning plane. The magnet arrangement has at least three electromagnets whose dipole axes are at least approximately parallel to the positioning plane and, viewed perpendicularly to the positioning plane, define a closed surface.
