What are Pot Magnets?<\/strong><\/h1>\n\n\n\n

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 an incredibly versatile and powerful tool that can be used in various applications, from industrial settings to magnet fishing to your everyday household needs. These magnets offer powerful clamping force and durability and provide outstanding versatility for a wide range of applications.<\/p>\n\n\n\n

If you are unsure about what a pot magnet is or how they work, don\u2019t worry, we will show you the incredible benefits of using pot magnets and help you find the perfect pot magnet for your needs!<\/p>\n\n\n\n

How Are Pot Magnets Made?<\/strong><\/h2>\n\n\n\n

A standard pot magnet is designed with a single magnetic face encased in a ferromagnetic steel casing. This extraordinary construction generates a concentrated clamping force that leaves conventional magnets in the dust, making them the go-to choice for clamping applications. The pot magnet’s magnetic circuit is optimized by removing air gaps and directing the magnetic field to the surface, providing a strong grip on ferrous-based materials.<\/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

Are Pot Magnets More Durable?<\/strong><\/h2>\n\n\n\n

One of the key advantages of pot magnets is their durability. The protective casing not only enhances the magnet’s clamping force but also shields it from impact and load-bearing damage. The casing is slightly raised over the facing of the magnet, allowing any clamping hits to be on steel rather than the magnet.<\/p>\n\n\n\n

This feature makes pot magnets an excellent choice for high-force applications, including magnetic fishing, where their durability proves invaluable in handling underwater conditions. The protective casing improves the resistance to corrosion by reducing exposure to corrosive conditions, further extending their usability in aquatic environments.<\/p>\n\n\n\n

What Materials Are Pot Magnets Made From?<\/strong><\/h2>\n\n\n\n

Pot magnets are available in a variety of materials, including Ferrite, Alnico, Neodymium, and Samarium Cobalt. Each material offers its unique properties, benefits, and drawbacks:<\/p>\n\n\n\n
