This NEO pot magnet is made of NEO magnet encased inside of a steel cup. The magnet is separated from the steel cup by a copper ring which creates a magnetic gap so the holding force is greatly increased when applied to a magnetic surface. A steal disc is provided to close the circuit during the transportation and storage, which needs to be removed when it is to be used. This holding device is used mostly in the metal industries, labs and machine shops. The holding power of this magnet is 29 lbs. The threaded hole on the top of the magnet is M5.
