Pot magnets and deep pot magnets made of neodymium and ferrite
Pot magnets - small and strong deep pot magnets
The special thing about a pot magnet is the increase in adhesive force due to a metal pot. The magnetic core lies in this, so that the adhesive surface remains free. Therefore, the adhesive force acts on one side of the magnet. The pot changes the magnetic flux and thus increases the force. So even relatively small magnets adhere very strongly. These magnets are versatile and are suitable for both commercial and private use. For example, they can be used as gripping magnets for industrial applications for transporting steel and iron parts. Therefore one speaks of deep pot. Such magnets are also very suitable for strong and quickly removable fastenings without drilling. Whether for trade fair and shop construction, as assembly magnets in private households, for hobby applications and other purposes.
Material of the magnetic core
The magnetic force depends on the material of the magnetic core. The cheapest, but also the weakest variant is the ferrite magnet. It is robust and can also be used outdoors. Neodymium magnets and SmCo magnets are considered high-energy magnets. They are often used where a very high adhesive force is required with small dimensions. Both variants are rare earth alloys. A samarium cobalt magnet can be used at very high and very low temperatures and is more corrosion-resistant than a neodymium magnet. Because of the limited availability of its raw materials, it is also more expensive. An NdFeB magnet is less brittle. Handling high-energy magnets requires compliance with certain safety precautions.
Different mounting options
Pot magnets are available for various mounting options, for example for screwing on. For this purpose there is a continuous cylinder bore with an internal thread in the middle. If there is an additional countersunk, nothing is protruding when using a suitable countersunk screw. Magnets with a non-continuous threaded bush on the back are screwed onto a pin with an external thread. There are also variants with threaded pins for screwing into a socket. If none of these mounting options are available, the magnets can also be glued into suitable openings. Different versions have a hook or an eyelet on the non-adhesive side, which can be easily and flexibly attached to metallic surfaces.
Other variants and accessories for pot magnets
The magnetic core is in a steel pot or stainless steel pot. Steel has a slightly higher adhesive force. Stainless steel is rustproof and is therefore also suitable for use outdoors. Further variants result from the type of manufacture of the casing, as a rotated or pressed housing. Thanks to the more complex turning, the pot can be manufactured more precisely. Rubber washers and caps are also available as accessories for the pot magnets. These protect sensitive surfaces from scratches.
Pot magnets are also called flat pot magnets, assembly magnets, fastening magnets or gripping magnets. The magnetic core is integrated in a round steel pot. The resulting magnetic short circuit increases the magnetic flux and thus the adhesive force. Because of the very low design that is possible from this, this magnet gets its name flat pot magnet.
Easily attached for secure attachment, for lifting or gripping, pot magnets are an ideal and detachable connection not only in metal, plant, trade fair or shop construction. Flat pot magnets are ideal for securely attaching objects to metallic surfaces. Pot magnets are available with a neodymium and ferrite magnetic core, with a threaded bush, countersunk or cylindrical bore or external thread.
As counterparts for pot magnets on non-metallic surfaces, you can also get metal discs to screw on and Metal discs to glue on.
