1. Pot magnets, also called Cup Magnets, Magnetic Holders or Magnet Hooks, are made of permanent magnet encased in a metal pot, and feature a hole, thread, boss or removable hook in centre of the magnets. The pot is an essential part of the magnetic circuit. the active magnet face is not enclosed. When Pot magnets hold any metal parts, the magnetic force in this circuit is stronger than that of alone magnet. It is the most efficient design for gripping, also provide an easy, non-destructive way to suspend objects or attach them to metal.
2. Material:
Magnet material: NdFeB, Alnico, SmCo, Ferrite.
Surface can be Zn, Ni, Cr, Epoxy, painting, Rubber cover etc.
3. Application:Hanging signs and lights, Fastening antennas, Holding tarps, Making retrieval tools, Holding through non-ferrous materials, Use for fastening or holding steel doors, nsertion into molds, insertion into fixtures, For car roof signs.

In addition, the greater strength of neodymium magnets has inspired new applications in areas where magnets were not used before, such as magnetic jewelry clasps, children’s magnetic building sets (and other neodymium magnet toys) and as part of the closing mechanism of modern sport parachute equipment. They also are the main metal in the formerly popular desk-toy magnets, “Buckyballs”, though some US retailers have chosen not to sell them due to child-safety concerns. Powerful NdFeB Ring Countersunk Magnet
Neodymium magnets are used as a surgically placed anti-reflux system which is a band of magnets surgically implanted around the lower esophageal sphincter to treat gastroesophageal reflux disease (GERD).
