Ring Magnet- A Ring Magnet is a circular shaped & creates a magnetic field. A ring magnet has a hole through the center. The hole’s opening may be at 90⁰ flat with the surface of the magnet or countersunk to accept a screw head maintaining a flush surface.
Ring magnets are used as Electric Motor Magnets, as a Ring Magnet levitation display, Bearing Magnets, in high-end speakers, for Magnetics Experiments & magnetic jewelry.
A Large selection of rings with over 45 different strong ring magnets available with outside diameter ranges from small rings 1/4″ to 4″ Large Ring Magnets in stock and Larger Ring Magnets up to an 8″ Ring magnet is available as a Custom Ring Magnet.
Ring Magnet grades include N42, N45, N48, N50, & N52, The residual flux density ranges of these ring magnets run from 13,500 to 14,400 Gauss or 1.35 to 1.44 Tesla.
Neodymium Ring Magnet Pull force ranges in this catergory run from 1 lb to 400 lbs. Epoxy Resin Coated Thin Neodymium Magnet Ring for Home Audio
Non-Neodymium Ring Magnet: Ceramic Ring Magnets or a Samarium Cobalt Ring Magnet.
Process of Making Rare Earth Magnets
The rare earth magnets are made by using different process involving various stages. The popular stages of the production of rare earth magnets are:
The first stage is the manufacture of rare earth element alloys.
The metal alloy is then finely powdered.
The next step involved is pressing of powder either isostatically or pressing through die process.
The particles so pressed are oriented. N35H Gray Epoxy Coating NdFeB Ring Permanent High-end Speaker Magnet
Sintering of the element is done accordingly.
The shapes are then sliced into desired shapes and sizes.
The coating is done thereafter. Epoxy Resin Plated Strong Magnet NdFeB Ring for Stereo Speakers
After finishing the above tasks, the finished shapes are magnetized.
At HERE, we sell custom Neodymium NdFeB magnets and custom magnetic assemblies so we can help you find the best fit for your project. Some of the common applications of the rare earth magnets are:
Motors and Generators
Automotive (clamps, sensors)
Separation (rods, grids, etc) – 10-12kG (22-26lbs) systems
High performance magnetic clamps and pot magnets
They are used in computer hard drives.
Rare earth magnets also find their utility in high-end speakers.
