There are five types of pot magnet: countersunk, internal threaded, through hole, bi-pole and stud. The pot magnets vary in their attachments, which allow them to be connected to different types of objects, such as supermarket signs and articulated gauging arms.
Countersunk pot magnets
Countersunk pot magnets are a type of a pot magnet with a countersunk hole in the magnetic face. The countersunk hole has a flat top on one magnetic face which tapers at a 82 degree angle towards the top of the shell, in the shape of a cone.

The countersunk hole aids the magnet in its attachment to non-ferromagnetic materials with a countersunk screw.
Internal threaded pot magnets
Internal threaded pot magnets
Internal threaded pot magnets are a type of pot magnet with a threaded hole through the centre. An internal threaded hole is a cylindrical hole with continuous grooves, known as threads, in a spiral pattern around its inside wall.

Internal threaded pot magnets can be used as magnetic bases for gauges, for example, an articulated gauging arm.
Through hole pot magnets
Through hole pot magnets
Through hole pot magnets have a hole through the centre, known as a boss. The boss allows the magnet to be attached to non-ferromagnetic items with a bolt.
Lifting a bike by through hole pot magnet
Through hole pot magnets can be used as retrieval magnets, which are used to pick up or retrieve ferromagnetic objects from hard-to-reach places. For example, you could use a retrieval magnet to pull a bicycle from a river.
Bi-pole pot magnet’s parts
Bi-pole pot magnets
Parts of a bi-pole pot magnet: shell, steel poles and magnet
Bi-pole pot magnets have a thin magnet in the centre with two mild steel poles on either side, inside a shell. This is known as a sandwich magnet system.
A sandwich magnet system makes the bi-pole pot magnet thirty-two times stronger than a standard magnet, for example, a bar magnet.
Internal threaded female stud pot magnet
Stud pot magnets
Stud pot magnets can either be a shallow or deep, and have a stud protruding from the top of the pot magnet’s case. The stud is the cylinder of stainless steel that protrudes from the surface of the magnet.
Stud pot magnets can be used to hold promotional signs from the ceilings of supermarkets.

| High maximum pull forces. NdFeB Pot Magnets and Neodymium Pot Magnets can be made with different temperature ratings and different magnet coating finishes. | Ideal for clamping and holding,Maximum temperature 100°C,Ideal for sub-assemblies | High power ‘rare earth’ magnet material. Slightly less powerful than neodymium but works up to 200 °C. (Neodymium is usually only usable up to 120°C.) | High maximum temperature: Alnico itself is capable of up to 550°C! Natural or painted finish available. |

| The rubber coated Neodymium (NdFeB) pot magnets are also suitable for fixing signs, plates, temporary lightings and sample parts scratch-free onto highly polished chrome-plated or painted mild steel (ferrous) surfaces. |
The strong neodymium magnets are embedded in a steel pot. The steel pot increases the adhesive force of the magnet on direct contact with a thick iron surface. |
They are ideal for incorporating into jigs and fixtures. They offer high holding forces on parts that are thick and clean with a good surface finish. |
The search engine uses the search neodymium magnet to locate and pick up metal objects from the bottom of reservoirs, wells, mines and other depths. Magnets allow lift even very heavy objects. |
