摘要：
The present invention is related to a method for fabricating an electromagnetic actuator. It is further related to an electromagnetic actuator and a charged particle device comprising such an actuator. According to the present invention, the method for fabricating is characterized by determining an optimal allocation of permanent magnets to reduce the magnetic stray field caused by deviations between the nominal and actual magnetization values of the permanent magnets. The invention further provides a charged particle device comprising an electromagnetic actuator fabricated using the method according to the invention.
