Neodymium Countersunk Cup Magnets/Neodymium mounting magnets, often called pot or cup magnets, are engineered with a protective steel cup on the N or S side of the magnet.

Neodymium Countersunk Cup Magnets, also referred to as mounting or cup magnets, are standard neodymium magnets with the N or S surface encased in a cup or pot-shaped layer made of ferromagnetic steel. This protective steel cup dramatically increases the sturdiness and impact resistance of the magnet – while also increasing the strength or pull force of the magnet itself at the same time.

Neodymium Countersunk Cup Magnets can also be made from a variety of materials, including neodymium, ceramic, and alnico, depending upon the application.

Most of our Neodymium Countersunk Cup Magnets come in paired N/S sets and are available in a range of sizes and strengths.

Neodymium Countersunk Cup Magnets offer a great value due to their ability to amplify an individual magnet’s strength. The pot is made of ferromagnetic steel, which means it can be magnetized by induction and develops its own magnetic field. This additional magnetic surface adds to the overall pull force of the magnet itself – making the magnet slightly stronger than it would be without the steel cup.
