The Benefits of Pot Magnets
Pot magnets, also known as cup or mounting magnets, are standard neodymium magnets that are encased in a protective steel housing on the N or S side. Engineered to provide superior sturdiness and impact resistance, this steel housing or “pot” is also ferromagnetic, thereby incrementally increasing the pull force of the magnet itself.
So, in addition to being exceptionally tough and resilient, neodymium pot magnets also provide a stronger pull force than a regular magnet with an equal N-rating and size. This is because the metal housing focuses the magnetic field in one direction, increasing the magnet's holding power.
Pot magnets give you much greater durability and pull force than regular neodymium magnets, and as a result, you get more magnet for your money.
