Pot magnets are magnets embedded in steel cups that aid in mounting and increase their holding power. They are typically used in fixed applications where they are attached to the surface by countersunk screws.
What is the structure of the pot magnet?
What is the extra protection of pot magnets?
What are the components of a typical pot magnet construction?
A typical pot magnet usually consists of a magnet contained within a housing or casing. The ferromagnetic housing is typically a plated mild steel material, but ferritic stainless steel (400 series) is also used and is popular for its corrosion resistance. View our range of pot magnets. When in direct contact with an iron-based surface, pot magnets typically clamp with a high concentration of magnetic force.
The clamping/tension force during direct contact is typically higher than that of conventional standard magnets. This is because the magnetic circuit is optimized for the clamping application (by removing the air gap from the magnetic circuit).
Pot magnets also protect the magnets within them, which really helps with high clamping force pot magnet applications. The steel housing ensures that the can magnets are more durable and protected from impact damage or load-bearing damage. Cups or housings protect the magnets - Ideally, can magnets are manufactured in such a way that they are slightly recessed relative to the surface of the cup ring, so any mechanical impact should be on the steel and not the magnet, thus limiting the risk of breakage.
When using pot magnets, the pot magnet can be pressed into place (not possible with magnets alone) - the cup protects the magnet and takes the pressure; specially manufactured pot magnets are required (we supply them). Protective housing improves corrosion resistance by reducing exposure to corrosive conditions.
A typical pot magnet has only one surface to which a magnetic field is applied, resulting in a concentrated clamping force. The magnetic surface is exposed from the housing. You may find a typical pot magnet equipped with a retaining plate that covers the magnet surface during transport or handling.
When designing can magnets, we design them to provide maximum pulling force relative to the magnet size - to do this, we design the air gap from the component's magnetic circuit. The ferromagnetic housing directs the magnetic field to the surface to be clamped for high efficiency. Thus, if the north side of the magnet is visible, the mild steel iron ring on the outside of the magnet acts as the south pole - effectively providing two poles on the clamping surface, leaving a short distance between the poles for the magnetic force to pass through the surface being clamped.
