FAQ on Permanent Ferrite Magnets

FAQ-Ferrite Permanent Magnets

Are ferrite magnets strong?

Generally speaking, it can be said that Ferrite (Ceramic) Magnets have moderate strength or pull force. Although not as strong as a Neodymium Magnet, they have more magnetic strength than Alnico magnetic products. In fact, large Ferrite magnets are very strong and the far-reaching magnetic field of Ferrite magnets make them highly suited to swarf metal collection and for metal recycling or metal decontamination. Small Ferrite magnets that are less than 30mm in diameter are not likely to be strong enough to support heavy weights or cause damage.

Do ferrite magnets rust?

No. This is the most beneficial feature and unique aspect of Ferrite magnetic material. If handled with care and not exposed to another strong magnetic field, a Ferrite magnet will not degrade and will keep its magnetic power for many years or even decades to come.

What are ferrite magnets used for?

Ferrite (Ceramic) magnetic material is considered an advantage in applications where high-temperature manufacturing occurs or for outdoor locations where corrosive forces such as saltwater and salt air are experienced. Ferrite magnets are also an ideal option when reducing product manufacturing costs is a bigger priority than the need for magnetic strength.

Ferrite magnets have been used for decades in loudspeakers and audio equipment technology. Other industries and technologies that use Ferrite magnetic material include:

Medical diagnostic equipment and instruments
Electric motors, generators and alternators
Hybrid and Electric Vehicles
Flexible magnetic sheets for advertising and promotional products. These contain a Ferrite powder and rubber compound.

Large Ferrite Ring Magnets are the main component in the Magnetron which is responsible for generating the heat energy inside a microwave oven.
