Pot magnets consist of a magnet contained within a housing or casing to ensure maximum performance whilst protecting the magnet from cracking or chipping when in use.<\/strong><\/p>\n\n\n\n

Pot magnets are ideal for clamping applications and provide extreme versatility for a wide range of applications.<\/p>\n\n\n\n

Pot magnets can be used across several industries and applications but if you are unsure about what a pot magnet is or how they work, don\u2019t worry, we have the answers right here for you!<\/p>\n\n\n\n

Typical Pot Magnet Construction<\/strong><\/h3>\n\n\n\n

A standard pot magnet has only one magnetic face which is exposed from the steel casing, creating a concentrated clamping force. A pot magnet typically clamps with a high concentration of magnetic force when in direct contact with ferrous-based surfaces, this will usually be higher than conventional standard magnets.<\/p>\n\n\n\n

This is because the magnetic circuit of a pot magnet is optimised for clamping applications, as air gaps are removed from the circuit. The ferromagnetic casing directs the magnetic field directly to the surface.<\/p>\n\n\n\n

For example, if a pot magnet has its south-facing showing, the ferrous ring of mild steel around the outside of the magnet will act as a north pole. Giving two poles on the clamping surface, making a short distance between poles for the magnetism to travel through the clamped surface.<\/p>\n\n\n\n

Extra Protection<\/strong><\/h3>\n\n\n\n

Pot magnets also protect the magnets inside them making pot magnets much more durable as they are protected from impact damage and load-bearing damage, which can be extremely useful for high clamping force applications.<\/p>\n\n\n\n

The casing should be ever slightly raised over the face of the magnet allowing any hits to be on the steel rather than the magnet.<\/p>\n\n\n\n

The protective casing improves the resistance to corrosion by reducing exposure to corrosive conditions.<\/p>\n\n\n\n

Pot Magnet Materials<\/strong><\/h3>\n\n\n\n

Pot magnets come in a variety of materials including Ferrite, Alnico, Neodymium, and Samarium Cobalt. Each material has its own properties, benefits, and weaknesses.<\/p>\n\n\n\n

Size for size Neodymium pot magnets will be the most powerful and Ferrite pot magnets will be cheaper and less powerful.<\/p>\n\n\n\n

Samarium Cobalt will be similar in strength to Neodymium but will perform better at higher temperatures.<\/p>\n\n\n\n

Alnico versions will have a range of performances depending on their shape, size, and design but would be best for high-temperature applications.<\/p>\n\n\n\n
