Ferrite Magnet hard magnetic material
The Ferrite Magnet is a ferritic metal oxide. In terms of electrical properties, the Ferrite Magnet has a much higher resistivity than metal and alloy magnetic materials, and has higher dielectric properties. The magnetic properties of Ferrite Magnet also exhibit high permeability at high frequencies. As a result, Ferrite Magnet has become a widely used non-metallic magnetic material in the field of high frequency and weak electricity. Since the magnetic energy stored in the Ferrite Magnet unit volume is low and the saturation magnetization is also low (usually only 1/3 to 1/5 of pure iron), it limits its low frequency and strong electrical energy The application of high power field.
Ferrite Magnet soft magnetic material
Such materials in the weaker magnetic field, easy to magnetize and easy demagnetization, such as zinc chrome Ferrite Magnet and nickel zinc Ferrite Magnet. Soft Ferrite Magnet is currently widely used, variety, large quantity, high output value of a Ferrite Magnet material. It is mainly used as a variety of inductance components, such as filter core, transformer core, radio core, and tape recording and video head, etc., is also a key component of magnetic recording components.
Ferrite Magnet hard magnetic material
Ferrite Magnet hard magnetic material is not easy to demagnetize magnetization, therefore, also known as permanent magnet material or constant magnetic material. Such as barium Ferrite Magnet, steel Ferrite Magnet and so on. It is mainly used in telecommunications devices in the sounders, pickups, speakers, a variety of instrument core and so on.
Ferrite Magnet
Magnetic properties of the magnetic material refers to the two perpendicular to each other under the action of a steady magnetic field and electromagnetic waves, the plane polarization of the electromagnetic wave in the material although a certain direction of transmission, but the polarization plane will continue to spread around the direction of rotation. Metal, alloy materials, although also have a certain degree of magnetic, but because of low resistivity, eddy current loss is too large, electromagnetic waves can not be deep into its internal, it can not be used. Therefore, the application of Ferrite Magnet rotating material magnetic properties, it has become a unique field of Ferrite Magnet. Most of the magnetic material and the transmission of microwave waveguide or transmission line composed of a variety of microwave devices. Mainly used for radar, communications, navigation, telemetry and other electronic equipment.
Ferrite Magnet moment
This refers to a Ferrite Magnet material with a rectangular hysteresis loop. Its characteristic is that when there is a small external magnetic field, it can make it magnetized and reach saturation, remove the external magnetic field, the magnetic remains the same as when saturated. Such as magnesium manganese Ferrite Magnet, lithium manganese Ferrite Magnet, etc. is the case. This Ferrite Magnet material is mainly used for a variety of electronic computer memory core and so on.
Ferrite Magnet
Such materials refer to Ferrite Magnet materials that are mechanically elongated or shortened in the direction of magnetic field when magnetized, such as nickel-zinc Ferrite Magnet, nickel-copper Ferrite Magnet and nickel-chromium Ferrite Magnet. Magnetostrictive materials are mainly used for electromagnetic energy and mechanical energy conversion of the transducer, for the magnetostrictive element for ultrasound.
