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

A long lasting magnet emits a magnetic field CZPT the require for any electricity
The metal shell aids the pot magnet by growing its keeping power and providing the magnet with additional strength and balance. 

Neodymium Rubber Coated Magnets Picture

What are the components of a pot magnet?



A pot magnet’s magnetic face is only uncovered on one side of the steel pot.
The north pole of a pot magnet is in the centre of the magnet, with the south pole about the outside the house edge.
The configuration of the magnetic poles creates a closed circuit when the magnet is hooked up to a ferromagnetic content, supplying a stronger hold. A closed circuit is exactly where the magnetic subject is trapped inside the ferromagnetic materials when it gets hooked up to the magnet.
This sort of magnetisation does direct to the magnetic subject getting sturdy, but not considerably reaching, as the traces only operate parallel to the magnet. Consequently, the pot magnet can only draw in ferromagnetic supplies when they are extremely near to the magnetic encounter.

Steel shell on a pot magnet

The metal shell is a casing for the magnet and shields it from any chipping or cracking from speak to with a hard area.
The steel pot offers toughness for the magnet, which would normally be very brittle, and enables threaded holes and studs to be inserted.
The steel shell aids the magnetic subject turn out to be up to thirty two instances more robust than other magnets by concentrating it to only one particular magnetic encounter. This means it can hold big objects these kinds of as supermarket indicators from a ceiling CZPT any additional support.
Some varieties 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 discipline when a pot magnet is not equipped with a spacer. This only occurs in American pot magnets, as brass or plastic shells are not at the moment CZPT in this place. 

Pot magnet spacer

A spacer acts as a barrier in-between the magnet and the metal shell to keep away from any demagnetising effects the metal may have on the magnet.
A spacer in a pot magnet can possibly be produced of brass or plastic. 

Rubber cap and rubber coating on a pot magnet

Pot magnets can have a rubber coating on leading of their steel shell which makes it possible for them to be utilized on surfaces the place the consumer does not want the magnet to scratch, these kinds of as on a car roof. 
If the pot magnet does not have a rubber coating, there is the alternative to purchase a rubber cap which is effortless to push on to the magnet and to eliminate.
The rubber provides the pot magnet with friction which allows the magnet to be clamped on vertical surfaces so they will not effortlessly slide off. Nonetheless, the rubber cap or rubber coating on a pot magnet generates an air gap which means the keeping abilities of the magnet can be lowered.
All sorts of pot magnets:

There are 5 varieties of pot magnet: bi-pole, countersunk, by means of gap, inside threaded, and stud.
Pot magnets are typically utilised as magnetic bases and magnetic holders for huge supermarket ceiling indications.
GME Neodymium Pot Magnets compliment our Alnico Pot Magnets by delivering large keeping powers in modest offers. These magnets are made to be “Minimal Profile,” but nevertheless include a tapped hole in the back wall for mounting.
The Neodymium Pot Magnets not only have a potent attraction even though in immediate contact with a work piece, but they also have outstanding discipline projection abilities.

NEODYMIUM with higher working 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 each Alnico and Neodymium, are a Level I or II food quality unit.
All GME Pot Magnets are Centerless Ground right after urgent to +.001″ / -.000″. The common tolerance on the length is +/-.015″. Tighter tolerances are CZPT upon request.

What are pot magnets used to?

Magnetic light-weight fittings

Internal threaded stud pot magnets can be utilized as component of a light fitting for a magnetic down light-weight. The magnet is attached to the finish of the light-weight to maintain it onto the metal in a ceiling. 

Exhibition show indicators

Countersunk pot magnets can be utilized to attach an exhibition screen indicator to a stand for marketing and advertising reasons, e.g. at a trade display.

Magnetic Holders

Internal threaded pot magnets with the added hook accent can be utilised to hold objects this sort of as mugs to a fridge doorway.

Magnetic bases

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

CZPT stops

Internal threaded stud pot magnets can be utilised as doorway stops to shield the door from closing all the way to the wall by keeping it open.

Tow lights

Through gap pot magnets can be attached to the base of a tow gentle to enable the person to connect the tow light-weight to the automobile to alert other street end users that their automobile has broken down.


Bi-pole pot magnets can be employed as jigs. A jig is a custom-created device created to handle yet another tool’s actions. The bi-pole pot magnet is press-fitted or glued in area on the jig to assist hold a non-ferromagnetic materials, this kind of as a piece of wooden, onto a ferromagnetic surface area although it is currently being drilled into.
