Abstract (en)
[origin: EP1300864A2] A magnet system (100) for an electromechanical switching device. The magnet system (100) having an electromagnetic coil system (106). An iron circuit (108) having a core (110) and a yoke (112) partially surrounded by the electromagnetic coil system (106). The iron circuit (108) having a magnetic field excited by the electromagnetic coil system (106). A permanent magnet (120) arranged outside of the iron circuit (108) that has field lines superimposed by the magnetic field of the electromagnetic coil system (106). The field lines of the permanent magnet (120) strengthen the magnetic field of the electromagnetic coil system (106) in a first region (130) and weaken the magnetic field of the electromagnetic coil system in a second region (128) such that the magnetic field in the first region (130) and the magnetic field in the second region (128) balance each other. <IMAGE>
