Pot Magnets are also known as Round Base Magnets or Round Cup Magnets, RB Magnets, cup magnets, are magnetic cup assemblies comprised of neodymium or ferrite ring magnets encased in a steel cup with a countersunk or counterbored mounting hole. With this type of design, the magnetic holding force of these magnetic assemblies is multiplied many times and is significantly stronger than individual magnets.
Pot magnets are special magnets, which especially the bigger ones, are used in the industry as industrial magnets. The magnetic core of pot magnets is made of neodymium and is sunk in a steel pot in order to intensify the adhesive force of the magnet. That is why they are called “pot” magnets.
