Ceramic pot magnets, also called ceramic cup magnets, are made from a large magnet encased within a steel shell. They are magnetic on one face only, creating a solid clamping force.
Ceramic pot magnets have many advantages and can be supplied with a tapped hole, a countersunk hole, a counter-bored hole, a threaded stud, or a threaded collar, all for convenient mounting. They can also be supplied with hooks and eyebolt attachments, ideal for hanging a variety of items.
How does a pot magnet differ from a regular magnet?
Magnetism is confined to one face only, where it is concentrated to give the maximum holding force possible for the size of the magnet. They are more resistant to chipping and cracking as they are protected by their steel shell.
