| Rules mount magnetic contacts strong> td> tr> tbody> table> contact opening up a magnet creating magnetic field and a contact whose status is changed by the presence of this field. In the air or neutral materials (wood, aluminum, plaster ...) the magnetic field is distributed as homogeneous around the magnet. Near ferromagnetic material (steel, soft iron) the magnetic field of the magnet is fully attracted and captured by this material and no longer acts in other directions. < br> 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. Son length: 42cm |
