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 (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.
Neodymium Ring Magnet Pull force ranges in this category run from 1 lb to 400 lbs.
