Cup / Pot magnets are designed for clamping directly onto a steel surface; they are made from a large magnet encased within a steel shell. They are magnetic on one face only, creating a solid clamping force. However, they should not be used to attract other magnets or attract through a gap as they have a shallow depth of magnetic field. 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 to 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.
