Rules mount magnetic contacts strong> td> tr> tbody> table> The
opening contact consists of a magnet and the magnetic field creating a contact whose state is changed by the presence of this field. In the air or neutral materials (wood, aluminum, plaster ...) the magnetic field is distributed uniformly around the magnet. A near ferromagnetic materials (steel, soft iron) the magnetic field of the magnet is fully attracted and captured by this material and no longer acting in other directions.
Therefore, it is necessary to remove enough magnets and magnetic media contacts using special spacers. To verify that material is ferromagnetic or not, use the magnet contact. If there is attraction between the magnet material, it is ferromagnetic.
