Ferrite Diametrically Magnetized Ring Magnet
Ferrite magnets are sintered permanent magnets composed of Barium or Strontium Ferrite.
This class of magnets, aside from good resistance to demagnetization, has the popular advantage of low cost.
Ferrite magnets are very hard and brittle and require specialized machining techniques.
Moreover, they should be machined in an unmagnetized state.
We have equipped to machine these materials to specifications.
Due to their low cost, Ferrite magnets enjoy a very wide range of applications,
from motors and loudspeakers to toys and crafts, and are the most widely used permanent magnets today.
Special machining techniques must be used to machine this material.
Magnetizing and Handling:
Ferrite magnets require magnetizing fields of about 10 kOe.
They can be magnetized with multiple poles on one or both pole surfaces.
No special handling precautions are required, except that large blocks of Ferrite magnets are powerful,
and care should be taken to ensure that they do not snap towards each other.
Up to about 840F, changes in magnetization are largely reversible,
while changes between 840F and 1800 F are re-magnetizable. For all Ferrite magnets,
the degradation of magnetic properties is essentially linear with temperature.
At 350 F, about 75% of room temperature magnetization is retained, and at 550 F, about 50% is retained.
Common Applications for Ferrite Magnets:
Ferrite magnets are widely used in motors, magnetic couplings,
for sensing, loudspeakers, holding-magnet systems, crafts, magnetic therapy, novelties, and toys.
