Pot magnets are special magnets, mainly used in the industry and known as industrial magnets. The magnetic core of a pot magnet is made up of neodymium and will be sunk into a pot which will intensify the force of said magnet, hence the name “Pot Magnets”.
There are four types of magnets:
Neodymium Iron Boron (NdFeB)
Samarium Cobalt (SmCo)
A pot magnet works with the help of a magnetic field by attaching itself to ferromagnetic materials or to non-ferromagnetic materials with the aid of fittings (such as threaded holes or studs) , the larger the force of the pot magnet the more material it can attract.
Pot magnets often have a centred borehole and a countersink which allows them to be screwed into the primer.
Pot magnets will come in various strengths, some have an adhesive force of up to 180kg. Even small pot magnets are very strong and can be used in model making and construction.
Pot magnets must be kept out of reach of children and electrical devices, even the small pot magnets can affect the function of electrical devices, some can even be destroyed by them. Also, people with a pacemaker or hearing aid should also avoid magnets in general.
Pot magnets will usually be stocked in various sizes and strengths and are suitable for a vast array of applications. They can also come with different mounting options. Just some of the pot magnets available are:
Car roof top magnets
Deep pot magnets
Pot magnets with countersunk mounting
Ferrite limpet pots
Pot magnets with studded threads
Pot magnets with internal threaded mounting
Pot magnets with threaded through hole
Pot magnets with through hole mounting
Shallow Pot Magnets
Pot magnets can also come in different finishes such as chrome, zinc or nickel or can be finished in a paint finish in various colours.
