About Neodymium Ring Magnets

About A Ring Magnet

These small wonders of physics are Coated with Ni+Cu+Ni Triple Layer Coating ,nickel, copper and nickel to give superior corrosion resistance and provide a smooth and clean finish like stainless steel.  

  • A Ring Magnet is a disc or 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 (contact CMS).

  • 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.

  • Ring Magnet Pull force ranges in this CMSs Neodymium Ring Magnet category run from 1 lb to 400 lbs (others available upon request).

  • See CMS' “Other Magnet Materials” category For a Non-Neodymium Ring Magnet: Ceramic Ring Magnets or a Samarium Cobalt Ring Magnet.

In Many cases, you can order a specialized extra coating of epoxy or plastic if your application requires it, making them even more valuable.

These Neodymium Magnetic rings are a whopping 10-14 times Stronger than the strongest ceramic ring magnets.  This is the stuff of science fiction, here & now!

So many applications for a strong ring magnet:  

  • Homes 

  • WorkShops

  • DIY

  • Science 

  • Hobby

  • Sorting metal items

  • Hold things up Hold things down

  • and Much More.

Safety Warning: These neodymium magnets are not for children.  They may break and cut severely. Children that may place things in their mouths should be kept away from these magnets.  If taken into the mouth these neodymium magnets may pinch across internal organ membranes with deadly results.

Ring Magnets have a special set of uses in the world of magnets.  A Ring magnet is specially suited to those magnetic repulsion experiments where you dangle 2 magnets from a string, but also:

  • Magnetic Jewelry

  • Medical Equipment

  • Mechanical control devices like pool water level controllers

  • magnetic actuators

  • Ultrasonic transducers

  • Robotics

  • Cryogenics applications
