PTFE Coated Neodymium Magnet provide an extra protection from shock to the magnet, and act as a tremendous barrier to many fluids. They are great for us as medical magnets, sensor magnets, and consumer electronics magnets.
Ring Magnets can be custom manufactured in different ways so that they can be magnetized in a specific direction. Below is an overview of the different direction of magnetization options, however, the direction of magnetization can only be set during the manufacturing process and cannot be changed once the magnet is made.
Through the Thickness: Ring magnets where a magnetic field travels from the ID of the ring magnet to the OD of the ring magnet.
Through the Diameter: Ring magnets where a magnetic field flows from the OD of the “north pole” to the OD of the “south pole”. The ID of the ring magnet will have a magnetic field that is straight and crosses uniformly across the ID.
Radially Magnetized: Radially magnetized ring magnets have the magnetic poles on the OD / ID instead of the face. Radial magnets are made as a single piece or in multiple pieces depending upon the size of the magnet.
Multi-Pole Magnetization on the Face: If a ring magnet is large enough it can be magnetized with multiple poles on the face in a North / South configuration.
Ideal for furniture fixings, hanging artwork and keeping doors and drawers closed, countersunk magnets have a central hole which allows them to be fixed to non-magnetic surfaces with a screw. Because these magnets have a PTFE-coating they are ideal for using to attract fragile or easily marked surfaces, the PTFE coating increases friction, softens impacts and prevents marking. Countersunk magnets with opposite poles on the countersunk face can be used to attract two surfaces or two opposing countersunk magnets with the same pole on the countersunk face can be used to create a damping, shock absorbing or repelling effect. Also available with the south pole on the countersunk face. other product:ptfe teflon coated cuntersunk magnets
