How to shield or guide the magnetic field

- Nov 22, 2017 -

Ferromagnetic materials can be used to shield the magnetic field, generally we use ordinary iron. However, it should be noted that the thickness of the iron plate, if the thickness of less than iron saturation in the state, it can only shield part of the magnetic field, some of the lines of force will still be divergent. The key to guide the magnetic field to form the magnetic circuit is to select materials with high permeability and suitable size and shape to reduce the magnetic flux leakage, that is to say, the magnetic yoke and the pole shoes in the magnetic circuit are properly arranged.
