What are the parts of a pot magnet?
The
configuration of the magnetic poles creates a closed circuit when the
magnet is attached to a ferromagnetic material, providing a stronger
hold. A closed circuit is where the magnetic field is trapped within the
ferromagnetic material when it becomes attached to the magnet.
This
type of magnetisation does lead to the magnetic field being strong, but
not far reaching, as the lines only run parallel to the magnet.
Therefore, the pot magnet can only attract ferromagnetic materials when
they are very close to the magnetic face.
Steel shell on a pot magnet
The steel shell is a casing for the magnet and protects it from any chipping or cracking from contact with a hard surface.
The
steel pot provides strength for the magnet, which would otherwise be
very brittle, and allows threaded holes and studs to be inserted.
The
steel shell helps the magnetic field become up to thirty two times
stronger than other magnets by concentrating it to only one magnetic
face. This means it can hold large objects such as supermarket signs
from a ceiling without 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
increases the magnetic field when a pot magnet is not supplied with a
spacer. This only occurs in American pot magnets, as brass or plastic
shells are not currently available in this country.
Pot magnet spacer
A
spacer acts as a barrier in-between the magnet and the steel shell to
avoid any demagnetising effects the steel may have on the magnet.
A spacer in a pot magnet can either be made of brass or plastic.
Rubber cap and rubber coating on a pot magnet
Pot
magnets can have a rubber coating on top of their steel shell which
allows them to be used on surfaces where the user does not want the
magnet to scratch, such as on a car roof.
If the pot magnet
does not have a rubber coating, there is the option to buy a rubber cap
which is easy to press onto the magnet and to remove.
The rubber
provides the pot magnet with friction which allows the magnet to be
clamped on vertical surfaces so they will not easily slide off. However,
the rubber cap or rubber coating on a pot magnet creates an air gap
meaning the holding capabilities of the magnet can be reduced.
All kinds of pot magnets:
There are five forms of pot magnet: bi-pole, countersunk, through hole, internal threaded, and stud.
Pot magnets are often used as magnetic bases and magnetic holders for large supermarket ceiling signs.
GME
The Neodymium
Pot Magnets not only have a potent attraction while in direct contact
with a work piece, but they also have excellent field projection
capabilities.
NEODYMIUM
with higher operating Temperatures and Intrinsic Coercive Forces are
available 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 Level I or II food grade unit.
All
GME Pot Magnets are Centerless Ground after pressing to +0.001 /
-0.000. The standard tolerance on the length is +/-0.015. Tighter
tolerances are available upon request.
Options
Various Tap Styles and Tap Depths.
Insulated (Brass Sleeved).
Shoulders and Machined Features on shell.
Protruding Pot Magnets.

What are pot magnets used to?
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.
Magnetic 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 stud 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
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.
