PERMANENT MAGNET / Ferrite

Ferrite


Specification
Raw materials for such magnets are abundant and inexpensive. Hard Ferrite Magnets have become the most widely specified magnetic materials. They are made isotropic or anisotropic. Anisotropic magnets are compressed in a magnetic field, resulting in one preferred direction of magnetization. Isotropic magnets are not oriented during manufacture and can be magnetized in several directions.

Ferrite
Exhibits an excellent energy product and have a high temperature coefficient.
High electric resistance.
Operating temperature range: -40C up to +200C.
Very hard and brittle, machining requires diamond tools.
Being oxides they do not corrode and are neither affected by climatic influences nor by many chemicals with the exception of some strong acids.
Application
Micro DC motors
Water Pumps Magnet for CD-ROMs Reed switches
Holding magnets Receivers Loudspeaker Hall-effect devices
