How to shield or guide the magnetic field?
Gauss Industrial Co.,Ltd | Updated: Jan 16, 2019

Ferromagnetic materials can be used to shield magnetic fields. Generally we use ordinary iron plates. However, it is necessary to pay attention to the thickness of the iron plate. If the thickness is not reached, the iron plate is in a magnetic saturation state, and only part of the magnetic field can be shielded, and some magnetic lines of force will still diverge. The key to guiding the magnetic field to form a magnetic circuit is to select a material with high magnetic permeability and a suitable size and shape to reduce magnetic leakage, that is, to properly arrange the yoke and the pole piece in the magnetic circuit.
