Ferrite Ring Magnets

The round magnets with a hole in the center are made of SrO or BaO and Fe2O3 by
molding and sintering, they are looks like discs and known as ring-shaped
permanent ferrite(ceramic) magnets. Ring shape ferrite (ceramic) magnets are
axially magnetized, and with magnetic poles on flat surface. Ring-shaped
permanent ferrite magnets are carried with anisotropic properties and wide size
range from small to large.

Characteristics Of Ferrite Ring Magnets
Magnetic ferrite ring have excellent corrosion resistance and can be used
without electroplating

Ferrite ring magnets are very hard and brittle, easy to break and difficult to
process.

The permanent ferrite rings has very good temperature resistance, with relative
magnetic stability up to 250 degrees Celsius.

Ferrite ring magnets have greater coercivity and strong resistance to
demagnetization.

Application Of Permanent Ferrite Magnet Rings
Ferrite magnet rings (also known as ceramic magnet rings) have less energy than
other permanent magnet rings, but advantages of resistance to demagnetism,
corrosion resistance, and low cost make them a popular choice for many
projects. Ferrite ring magnets of various sizes are often used in loudspeakers,
household appliances, torque drivers and resonance imaging. Holding, closing
doors, joinery and lighting fixtures are other applications of permanent
ferrite rings.
