Ring Shape Permanent Neo Magnet
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. N50 Super Strong Ring Rare Earth NdFeB Large Magnet Diameter 73.02mm
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. Powerful Magnet Rare Earth Neo Ring N35UH Magnets for Loudspeaker
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.

These powerful ring magnets neodymium are comprised of strong neodymium material makes them the strongest ring magnets of their size commercially available. These Ring magnets are axially magnetized so the north and south poles are on the flat surfaces, and the red line on one side of the ring magnet denotes which side the north pole is on. Neodymium ring magnets are strong magnets & are unique because of their extreme resistance to demagnetization. These ring magnets will only lose their magnetism if they’re heated above 176 degrees Fahrenheit. Our Strong Neodymium Ring Magnets have a special set of uses in the world of magnets. Ring magnets are specially suited to those magnetic repulsion experiments where you dangle 2 magnets from a string, but also Jewelry and in the medical field. One magician we know even wanted one that looks like a wedding ring. Hmmm, the methodology for the trick would be hiding in plain site.

Ring Magnets Neodymium At HSMAG Magnets For Sale
Here at Magnets For Sale & HSMAG Magnetics we carry neodymium ring magnets with epoxy coatings and with a countersunk hole already drilled in the middle to attach it to nonmetallic materials such as wood or plastic. These Ring magnets even allow the screw’s head to reside below or even with the face of the Ring magnets to ensure it does not interfere with the ring magnet function.
