Functioning of the neodymium pot magnets with steel pot: The strong NdFeB magnets are installed in a steel pot. This metal housing protects the neodymium magnet from damage and increases the adhesive force. In order to achieve an optimal adhesive force, the pot magnet must rest directly on the metallic surface. A thin sheet of iron or paint can reduce the adhesive force very quickly. The adhesive force only acts on the open magnet side, since the steel pot shields the magnetic effect. Neodymium Cap Pot Magnet with Cylindrical Borehole D60mm
Special feature: The attachment is done here by e.g. a Torx or Allen screw. The screw can be screwed in flush in the central hole and the magnet can be securely screwed to the wall / ceiling. Metallic counterparts then adhere magnetically to this pot magnet. The maximum operating temperature is 80 ° C.
With lower adhesive forces you can also use these pot magnets with ferrite core. The holding magnets / assembly magnets / pot magnets are used particularly often in industry, trade fairs and assembly. The strong pot magnets are also indispensable in the advertising sector / display construction / lighting sector. Neodymium Screw-on Pot Magnet D50.8mm
