4 Tips Of Permanent Ferrite Magnet Application

1.Application in microwave communication technology:

Permanent ferrite magnet are used in radar technology, satellite communications, remote control telemetry technology, electronic tracking, electronic countermeasures technology. Magnetrons are used in magnetron tubes, magnetron traveling wave tubes, cathode ray tubes, circulators, etc.

2.Application in electrical engineering:

More than one-third of the output of Permanent ferrite magnet materials is used to manufacture various permanent magnet motors. The advantages of permanent magnet motors are copper saving, electricity saving, light weight, small size and high specific power. Electric bicycle motors, computer-driven motors, lathes, etc., measuring motor speed and rotation speed, elevator traction machine motors, mahjong motors, refrigerator air-conditioning motors, wind power motors, automobile starting motors, etc. are extremely wide-ranging.

Such as speakers (loudspeakers), microphones, hearing aids, stereo headphones (MP3, MP4), telephone receivers and electro-acoustic sensors, etc.

4.Application in magnetic mechanical engineering:

Magnetic machinery includes magnetic actuators, magnetic gears, magnetic brakes, magnetic clamps, magnetic fishing devices, magnetic bearings, magnetic pumps, magnetic valves, magnetic sealing doors, magnetic locks and permanent magnet jacks, Permanent ferrite magnet , etc.

A permanent ferrite magnet is an object made from a magnetized material and creates its persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. Materials with the name ferromagnetic can be magnetized, which are also the ones that are strongly attracted to a magnet. These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone. Although ferromagnetic materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to a magnetic field by several different types of magnetism.

※ Surface treatment for ferrite

A significant advantage of the strongest permanent magnet is that no surface treatment is needed because ferrite is inert and does not oxidize. It is always possible to coat ferrite magnets with various epoxy coatings when desired, for example, from the hygiene point of view.

※ Precautions when working with ferrite

Ferrite is hard and brittle. Pieces break off when the material falls. So it must be kept in mind when working with these magnets.
