This ceramic ring magnet is made of grade 8 hard ferrite magnetic material. Ceramic magnets are the most economical type of magnet available and are the most widely used. It is not the strongest magnet type but still provides sufficient holding power for most applications. The holding power of this magnet is about 3.6 lbs.
Industrial grade high quality ceramic ring magnet
Grade 8 with 3,850 internal Gauss. 3.6 lb holding power per magnet
Great item for speakers, science projects and magnetic therapy.
Magnetized through thickness so that the N and S poles are on the flat surfaces.
High quality magnet made under ISO 9001 quality systems
1. Keep it away from pacemakers and kids under 10 years old.
2. All magnets are fragile and may chip or shatter. But if used properly, it can serve you for a lifetime.
Ceramic ring magnets, also known as Ferrite Ring Magnets, come in a wide range of sizes. They are often used in loudspeakers and in resonance imaging and torque drives. Other applications for this permanent magnet include holding, door closures, joinery, and light fixtures. Ceramic Rings are similar to Ceramic Discs but with a hole in the middle, which makes them a versatile magnet option. One popular application is the fishing game, tied on a piece of string, or to pick up pins and needles. Ferrite magnets have less magnetic strength (due to the hole) but their inexpensive pricing makes them a customer favorite.

Ceramic magnets are manufactured using powder technology techniques, meaning they can easily be magnetized or attracted to a magnet. Ferrites can be divided into two families based on their resistance to being demagnetized (magnetic coercivity).
Ceramic Ring Features
Ceramic rings offer economical magnet power for price sensitive applications when you need low cost, good holding strength, and great value.
Ceramic ring magnets are a dark charcoal gray in color and do not appear metallic.
Ceramic magnets are not suited for high-temperature applications (over 250° C)
We stock ceramic ring magnets in Grade 5, magnetized through the thickness. Grade 8 is also available by request; that is generally used in more demanding technical applications.
