A pot magnet is a permanent magnet encased in a steel shell, which is occasionally called a pot, consequently the title ‘pot’ magnet. 

A everlasting magnet emits a magnetic discipline CZPT the need to have for any electrical energy
The steel shell helps the pot magnet by growing its holding energy and supplying the magnet with added strength and stability. 

What are the parts of a pot magnet?


A pot magnet’s magnetic experience is only exposed on one particular facet of the steel pot.
The north pole of a pot magnet is in the centre of the magnet, with the south pole close to the exterior edge. 
The configuration of the magnetic poles generates a closed circuit when the magnet is hooked up to a ferromagnetic content, offering a much better keep. A shut circuit is where the magnetic subject is trapped inside of the ferromagnetic content when it becomes connected to the magnet.
This type of magnetisation does guide to the magnetic subject getting strong, but not significantly achieving, as the strains only run parallel to the magnet. For that reason, the pot magnet can only appeal to ferromagnetic resources when they are extremely shut to the magnetic encounter.

Steel shell on a pot magnet

The steel shell is a casing for the magnet and safeguards it from any chipping or cracking from get in touch with with a difficult floor.
The metal pot offers power for the magnet, which would in any other case be extremely brittle, and makes it possible for threaded holes and studs to be inserted. 
The steel shell helps the magnetic subject turn out to be up to 30 two occasions stronger than other magnets by concentrating it to only one magnetic face. This means it can hold massive objects this kind of as grocery store indicators from a ceiling CZPT any further assist.
Some kinds of pot magnet can also be encased in a brass or plastic shell. The brass and plastic offer the magnet with a non-ferromagnetic shell which raises the magnetic discipline when a pot magnet is not provided with a spacer. This only takes place in American pot magnets, as brass or plastic shells are not presently CZPT in this region. 

Pot magnet spacer

A spacer functions as a barrier in-among the magnet and the steel shell to avoid any demagnetising effects the metal could have on the magnet. 
A spacer in a pot magnet can both be created of brass or plastic. 

Rubber cap and rubber coating on a pot magnet

Pot magnets can have a rubber coating on leading of their metal shell which permits them to be utilized on surfaces the place the user does not want the magnet to scratch, these kinds of as on a automobile roof. 
If the pot magnet does not have a rubber coating, there is the option to acquire a rubber cap which is easy to push onto the magnet and to get rid of. 
The rubber provides the pot magnet with friction which makes it possible for the magnet to be clamped on vertical surfaces so they will not simply slide off. Nevertheless, the rubber cap or rubber coating on a pot magnet generates an air hole which means the keeping abilities of the magnet can be lowered.
All sorts of pot magnets:

There are 5 kinds of pot magnet: bi-pole, countersunk, by means of gap, inside threaded, and stud.
Pot magnets are often utilised as magnetic bases and magnetic holders for big supermarket ceiling signs.
GME Neodymium Pot Magnets compliment our Alnico Pot Magnets by delivering big keeping powers in small offers. These magnets are made to be “Minimal Profile,” but still include a tapped gap in the back wall for mounting.
The Neodymium Pot Magnets not only have a powerful attraction although in direct contact with a work piece, but they also have superb discipline projection capabilities.

NEODYMIUM with greater working Temperatures and Intrinsic Coercive Forces are CZPT in these Pot Magnets. Samarium Cobalt and Stainless shells and shields are also made. The all Stainless Pot Magnets, for the two Alnico and Neodymium, are a Degree I or II foodstuff quality unit.
All GME Pot Magnets are Centerless Floor right after urgent to +.001″ / -.000″. The common tolerance on the size is +/-.015″. Tighter tolerances are CZPT upon ask for.

  • A variety of Faucet Types and Faucet Depths.
  • Insulated (Brass Sleeved).
  • Shoulders and Machined Functions on shell.
  • Protruding Pot Magnets.
  • Metric and CZPT Dimensions

What are pot magnets used to?

Magnetic light fittings

Interior threaded stud pot magnets can be employed as component of a light-weight fitting for a magnetic down gentle. The magnet is hooked up to the finish of the gentle to maintain it onto the steel in a ceiling. 

Exhibition show indicators

Countersunk pot magnets can be employed to attach an exhibition show indicator to a stand for advertising functions, e.g. at a trade present.

Magnetic Holders

Interior threaded pot magnets with the included hook accessory can be used to dangle items this sort of as mugs to a fridge doorway.

Magnetic bases

Deep interior threaded pot magnets can be employed as a magnetic base for gauges e.g. an articulated gauging arm. An articulated gauging arm is employed to exactly situation objects within metrology (the science of measurement).

CZPT stops

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

Tow lights

By way of gap pot magnets can be attached to the base of a tow light-weight to permit the consumer to attach the tow light to the vehicle to alert other road customers that their auto has damaged down.


Bi-pole pot magnets can be utilised as jigs. A jig is a custom made-manufactured device designed to manage yet another tool’s movements. The bi-pole pot magnet is push-equipped or glued in spot on the jig to help hold a non-ferromagnetic substance, this sort of as a piece of wooden, onto a ferromagnetic surface although it is currently being drilled into.
