Cup / Pot MagnetsCup magnets are powerful rare earth neodymium magnets embedded in a protective steel cup or pot. The steel protects the back and sides of the magnet, leaving one face open for attachment.The metal shield blocks and partially redirects the magnetic field, so the magnetism that would have otherwise been wasted is redirected to face the attaching surface. This magnetic circuitry makes these magnets stronger than conventional magnets when attaching to metal surfaces. |
