What is Pot Magnets?

Pot magnets are special magnets, which especially the bigger ones, are used in the industry as industrial magnets. The magnetic core of pot magnets is made of neodymium and is sunk in a steel pot in order to intensify the adhesive force of the magnet. That is why they are called "pot" magnets.

The steel shell helps the pot magnet by increasing its holding power and providing the magnet with added strength and stability.

Pot magnets are often used as magnetic bases and magnetic holders for large supermarket ceiling signs.

There are five forms of pot magnet: bi-pole, countersunk, through hole, internal threaded, and stud.

How does a pot magnet work?

A pot magnet works by attaching itself to ferromagnetic materials with the help of its magnetic field, or to non-ferromagnetic materials with the help of fittings (such as studs and threaded holes) on the top of its steel shell.

The steel shell on a pot magnet means that it can hold a greater amount of ferromagnetic material. This is because the steel pot causes the magnetic force to be contained within the shell on the ferromagnetic surface, making the magnetic pull stronger.

This is in comparison to a horseshoe magnet or bar magnet where the magnetic field lines are splayed around the magnet and are not focused on the surface the magnet is attaching itself to.

As the magnetic field is concentrated in one area, the magnet will not be allowed to attract ferromagnetic materials over a large air gap. This is because the magnetic field lines will not stretch out beyond the sides of the shell.

The pull force of a pot magnet attracts the ferromagnetic material to the magnet, holding it in place. The larger the pull force of the pot magnet, the more material it can attract.

xq07

A magnet' s pull force is determined by a number of different factors; for example, how the magnet has been coated and any damage which may have occurred to the surface of the magnet.

Size of pot magnet

Neodymium magnets can be made into different shapes / sizes according to customer requirements. Such as pot magnet hook magnet, pot magnet fishing magnet, pot magnet rubber coated magnet, pot magnet pin magnet, office magnet, pot magnet magnetic elevator, pot magnet magnetic tools, etc. We have our standard size of pot magnets and of course we’re also able to custom the pot magnets according to your special requests. NdFeB pot magnets are round / block neodymium magnets with iron shell components. The size and magnetic force of all neodymium tank magnets can be customized according to your request. Contact us for your pot magnets.

What is pot magnet used for?

xq03

There are many ways to use a pot magnet. To illustrate their applicability, here are a few examples:

Magnetic light fittings
Internal threaded stud pot magnets can be used as part of a light fitting for a magnetic down light. The magnet is attached to the end of the light to hold it onto the metal in a ceiling.

Exhibition display signs
Countersunk pot magnets can be used to attach an exhibition display sign to a stand for marketing purposes, e.g. at a trade show.

Holders
Internal threaded pot magnets with the added hook accessory can be used to hang items such as mugs to a fridge door.

Magnetic bases

Deep internal threaded pot magnets can be used as a magnetic base for gauges e.g. an articulated gauging arm. An articulated gauging arm is used to precisely position objects within metrology (the science of measurement).

Door stops

Internal threaded stup pot magnets can be used as door stops to protect the door from closing all the way to the wall by holding it open.

Tow lights

Through hole pot magnets can be attached to the bottom of a tow light to enable the user to attach the tow light to the car to warn other road users that their car has broken down.

Jigs

Bi-pole pot magnets can be used as jigs. A jig is a custom-made tool created to control another tool’s movements. The bi-pole pot magnet is press-fitted or glued in place on the jig to help hold a non-ferromagnetic material, such as a piece of wood, onto a ferromagnetic surface whilst it is being drilled into.
