A pot magnet is a everlasting magnet encased in a metal shell, which is often referred to as a pot, hence the title ‘pot’ magnet. 

A long lasting magnet emits a magnetic field CZPT the want for any electrical power
The steel shell aids the pot magnet by growing its keeping electrical power and offering the magnet with extra toughness and steadiness. 

What are the parts of a pot magnet?


A pot magnet’s magnetic experience is only exposed on 1 aspect of the metal pot.
The north pole of a pot magnet is in the centre of the magnet, with the south pole about the outside edge. 
The configuration of the magnetic poles generates a shut circuit when the magnet is hooked up to a ferromagnetic substance, providing a much better keep. A shut circuit is where the magnetic discipline is trapped in the ferromagnetic material when it turns into attached to the magnet.
This kind of magnetisation does direct to the magnetic discipline currently being strong, but not significantly reaching, as the traces only operate parallel to the magnet. Therefore, the pot magnet can only attract ferromagnetic supplies when they are quite near to the magnetic face.

Metal shell on a pot magnet

The steel shell is a casing for the magnet and protects it from any chipping or cracking from speak to with a difficult surface.
The steel pot supplies energy for the magnet, which would otherwise be very brittle, and makes it possible for threaded holes and studs to be inserted. 
The steel shell aids the magnetic field turn out to be up to 30 two occasions much better than other magnets by concentrating it to only one magnetic experience. This signifies it can keep huge objects this sort of as grocery store symptoms 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 provide the magnet with a non-ferromagnetic shell which boosts the magnetic area when a pot magnet is not provided with a spacer. This only happens in American pot magnets, as brass or plastic shells are not at present CZPT in this place. 

Pot magnet spacer

A spacer functions as a barrier in-between the magnet and the metal shell to stay away from any demagnetising outcomes the steel might have on the magnet. 
A spacer in a pot magnet can possibly be manufactured of brass or plastic. 

Rubber cap and rubber coating on a pot magnet

Pot magnets can have a rubber coating on best of their metal shell which permits them to be utilised on surfaces the place the consumer does not want the magnet to scratch, this kind of as on a automobile roof. 
If the pot magnet does not have a rubber coating, there is the alternative to purchase a rubber cap which is straightforward to push on to the magnet and to remove. 
The rubber gives the pot magnet with friction which permits the magnet to be clamped on vertical surfaces so they will not easily slide off. Nonetheless, the rubber cap or rubber coating on a pot magnet results in an air gap meaning the holding abilities of the magnet can be reduced.
All kinds of pot magnets:

There are five varieties of pot magnet: bi-pole, countersunk, by way of hole, inside threaded, and stud.
Pot magnets are often used as magnetic bases and magnetic holders for large grocery store ceiling signs.
GME Neodymium Pot Magnets compliment our Alnico Pot Magnets by providing large holding powers in little packages. These magnets are created to be “Low Profile,” but nevertheless include a tapped gap in the back again wall for mounting.
The Neodymium Pot Magnets not only have a potent attraction even though in immediate make contact with with a operate piece, but they also have excellent subject projection capabilities.

NEODYMIUM with larger operating Temperatures and Intrinsic Coercive Forces are CZPT in these Pot Magnets. Samarium Cobalt and Stainless shells and shields are also manufactured. The all Stainless Pot Magnets, for both Alnico and Neodymium, are a Stage I or II food grade device.
All GME Pot Magnets are Centerless Floor right after pressing to +.001″ / -.000″. The normal tolerance on the length is +/-.015″. Tighter tolerances are CZPT on request.

  • Different Tap Designs and Tap Depths.
  • Insulated (Brass Sleeved).
  • Shoulders and Machined Characteristics on shell.
  • Protruding Pot Magnets.
  • Metric and CZPT Measurements

What are pot magnets utilized to?

Magnetic light fittings

Inner threaded stud pot magnets can be employed as part of a light-weight fitting for a magnetic down light-weight. The magnet is connected to the conclude of the light-weight to hold it on to the metallic in a ceiling. 

Exhibition display symptoms

Countersunk pot magnets can be utilised to attach an exhibition show signal to a stand for advertising and marketing reasons, e.g. at a trade present.

Magnetic Holders

Inside threaded pot magnets with the additional hook accessory can be used to hang products such as mugs to a fridge door.

Magnetic bases

Deep inside threaded pot magnets can be utilised as a magnetic base for gauges e.g. an articulated gauging arm. An articulated gauging arm is utilized to exactly position objects inside of metrology (the science of measurement).

CZPT stops

Internal threaded stud pot magnets can be employed as door stops to defend the door from closing all the way to the wall by keeping it open up.

Tow lights

By means of hole pot magnets can be connected to the base of a tow light-weight to enable the consumer to attach the tow light-weight to the vehicle to alert other street customers that their car has damaged down.


Bi-pole pot magnets can be employed as jigs. A jig is a custom-created device designed to manage yet another tool’s movements. The bi-pole pot magnet is push-fitted or glued in spot on the jig to assist hold a non-ferromagnetic material, these kinds of as a piece of wood, onto a ferromagnetic floor although it is becoming drilled into.
