Ring Neodymium Magnets are designed to be attached directly to a steel surface. This is a large magnet that serves as a base, enclosed within a steel casing, its magnetism is on one side only and creates a solid holding force, without the need for any electricity.
　　Nylon injection gives the magnet excellent mechanical properties
　　Allows thousands of operations without wear and tear.
　　Ideal for continuous movements.
　　Eliminates metal noises in automatic operations.
　　Corrosion resistant, very suitable for wet surfaces.
　　The resin coating allows handling and working without damaging any surface.
　　The steel cover helps the magnetic bases to increase their holding power, after providing greater strength and stability. However, magnetic bases cannot be used to attract other magnets or to attract them through a hole as they have a shallow depth of magnetic field.
　　Parts of the magnet:
　　Magnet. The north pole of the magnetic bases is in the center of the magnet, with the south pole around the outer edge. The configuration of the magnetic poles creates a closed circuit when the magnet is attached to a ferromagnetic material, which provides a stronger grip. A closed circuit is where the magnetic field is trapped inside the ferromagnetic material when it attaches to the magnet.
　　Steel housing. The steel cover is a casing for the magnet and protects it from any chipping or cracking from contact with a hard surface and any demagnetizing effect. Magnetic bases provide resistance for the magnet and help make the magnetic field up to thirty-two times stronger than other magnets by concentrating it on a single magnetic face. This means that it can hold large objects such as supermarket signs from the ceiling without any additional support.
　　Separator. A spacer or separator acts as a barrier between the magnet and the steel casing to prevent any demagnetizing effect the steel may have on the magnet. This element can be made of brass or plastic.
　　Rubber. Magnetic bases can have a rubber coating on the top of their steel casing, allowing them to be used on surfaces where the user does not want the magnet to scratch, such as the roof of a car.
　　What are the uses of pot magnets?
　　There are many ways to use magnetic bases and these are some of their applications:
　　Lamps. The magnet is attached to the end of the light to keep it on the metal in a roof.
　　Exhibition posters. They can be used to place an exhibition poster on a stand for marketing purposes, for example, at a trade fair.
　　Hooks. Magnetic bases can be fitted with an additional hook, and can be used to hang items such as cups on the refrigerator door.
　　Meter base. An articulated measuring arm, for example, can also be used as a magnetic base for meters. An articulated measuring arm is used to accurately position objects.
　　Door stops. Among the uses of magnetic bases also stand out as door stops, to prevent the door from closing to the wall keeping it open.
　　As has been said, the operation of magnetic bases is basic: They attach to ferromagnetic materials, unlike permanent magnets, where the magnetic field lines extend around the magnet and do not focus on the surface to which the magnet attaches.
　　Since the magnetic field is concentrated in one area, it does not allow the magnet to attract ferromagnetic materials through a large air space. This is because the magnetic field lines will not stretch beyond the sides of the cover.
