Displacement force: The indicated adhesive force was measured perpendicular to the surface to which the magnet should stick. It takes a lot less strength to move the magnet sideways. Therefore, you won’t be able to put as much strain on a pot magnet if you use it on a wall as opposed to using it on the ceiling.Features of screw-on pot magnets
Principle: The strong neodymium magnets are embedded in a steel pot. The steel pot increases the adhesive force of the magnet on direct contact with a thick iron surface. If there is no direct contact with the counterpart, or if the steel plate is thin, painted or rough, you won’t be able to put as much strain on it.
Rust: These magnets are not rust-proof and therefore intended for dry indoor use.
The Pot Magnet with Through Hole Mounting also exists in a rubber coating version to provide additional friction to minimise sliding along a surface. Pot NdFeB Magnet with Cylinder Borehole Φ16mm
NdFeB Hole Pot Magnets are best for small sized magnetic products with maximum pull strength (ideally when in direct contact with ferromagnetic e.g. mild steel surfaces). The actual pull force achieved is dependent on the surface that is being clamped onto (material type, thickness, flatness, friction levels, etc), its quality (e.g. rust free), its size (thickness plus total surface area), etc.
We offer Pot Magnets in a silver (chrome, zinc or nickel) finish, a white paint finish, a red paint finish, black rubber coated finish and ferritic stainless steel finish, etc.
