Ferromagnetic materials can be used to shield the magnetic field, normally we use ordinary iron plate. But it's important to note that the thickness of the plate, if the thickness of the short, iron plate in a magnetic saturation state, part of the magnetic field, only the shield part of the magnetic field lines are still divergent. Guiding magnetic field formation of magnetic circuit is the key to choose the high permeability material as well as the appropriate size and shape, reduce the magnetic flux leakage, the yoke of magnetic circuit and pole shoe reasonable configuration. |
