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.
This steel cup or pot helps protect the magnet from impact and increases its magnetic pull force as well. As a result, these magnets provide superior value (i.e., more pull force for a lower cost) - with plenty of versatility.

What are pot magnets?
Pot 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. As a result, cup magnets also deliver increased value by providing added pull force at a lower cost.
Commonly used for holding, mounting, and positioning applications - pot magnets are also utilized to hold metal objects in place, such as doors, windows, and cabinets. They are also widely used for attaching signs, lights, shelves, artwork, and other fixtures to metal surfaces. Cup magnets are also extensively integrated into machinery-related applications, as they can be harnessed to hold metal parts in place during the manufacturing process.
Pot magnets can also be made from a variety of materials, including neodymium, ceramic, and alnico, depending upon the application.
Most of our neodymium pot magnets come in paired N/S sets and are available in a range of sizes and strengths.
What makes pot magnets so strong?
Pot 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.
This is why steel is often used in the construction of magnets, such as in the housing of pot and cup magnets. It makes the magnet more effective at attracting and holding other ferromagnetic materials - as well as providing added value for an improved bottom line.
