Pot magnets and deep pot magnets made of neodymium and ferrite
The special thing about a pot magnet is that its adhesive force is increased by a metal pot. The magnetic core is in this so that the adhesive surface remains free. Therefore, the adhesive force only acts on one side of the magnet. The pot changes the magnetic flux and thus increases the force. As a result, even relatively small magnets stick very strongly. Pot magnets are versatile and suitable for both commercial and private use. For example, they can be used as gripping magnets for industrial applications to transport steel and iron parts. That is why one also 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.
Pot magnets: The 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. On the other hand, ferrite magnets are very robust and corrosion-resistant and can therefore also be used outdoors.
High-energy magnets are neodymium magnets and SmCo magnets. They are often used where very high holding power or adhesion is required with small dimensions. Both variants are alloys with rare earths. A samarium cobalt magnet can be used at very high and very low temperatures and is more resistant to corrosion than a neodymium magnet. Due to the limited occurrence of its raw materials, it is more expensive. A NdFeB magnet is less brittle.
Handling high energy magnets requires certain safety precautions to be taken. For example, you should never use them near children.
Different attachment options for magnetic pots
You can buy pot magnets in different mounting variants:
- Countersunk pot magnet
There is a continuous hole with an internal thread in the middle of the pot magnet. If there is also a countersink, nothing protrudes if you use a suitable countersunk screw.
- Pot magnets with threaded bush
Magnets with a non-continuous threaded socket on the back are screwed onto a pin with an external thread. There are also variants with a threaded pin for screwing into a socket.
If none of these mounting options are available, the magnets can also be glued into suitable openings. Various versions have a hook or an eyelet on the non-adhesive side, which can be easily and flexibly attached to metal surfaces.
Further variants and accessories for pot magnets with or without thread
The magnet core is in a steel pot or stainless-steel pot. Steel causes a slightly higher adhesive force. Stainless steel is rustproof and is therefore also suitable for outdoor use. Other possible uses arise from the way the casing is manufactured. It can be a turned or pressed case. The pot can be manufactured more precisely due to the more complex turning. Rubber discs and caps are also available as accessories for the pot magnets. These protect sensitive surfaces from scratches.
Pot magnets are also called deep pot magnets, mounting magnets, fastening magnets, or gripping magnets. With them, the magnetic core is integrated into a round steel pot. The resulting magnetic short circuit increases the magnetic flow and thus the adhesive force. This magnet gets its name from the resulting very low design.
What distinguishes pot magnets?
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. Deep pot magnets are ideal for securely attaching objects to metal surfaces.
Pot magnets are available with neodymium and ferrite magnet cores, 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 from us.
Buy pot magnets: All advantages briefly
Pot magnets have many advantages. Here is an overview of the most important ones:
- Pot magnets have a strong adhesive force, although the design is flat
- Depending on the material, they can also be used at high temperatures and unfavorable weather conditions
- Both purely metallic and rubberized pot magnets are available
- You can use pot magnets with eyelets or hooks for magnet fishing, for example
- Demagnetization is almost impossible with our magnets - only possible with strong electromagnets
- All pot magnets are available in different versions
