The concept of different magnetic trap, magnetic board, Overband magnetic separator?

The magnetic trap with microwave magnetic unique, such as tensor properties, permeability of Faraday rotation, resonance absorption, field shift, phase shift, birefringence and spin wave effect. The device is mainly used as the microwave energy transmission and conversion, commonly used with isolators, circulators, filter Magnetic Trap, attenuator, phase shifter, modulators, switches, limiter and delay lines, there is still in the development of magnetic surface waves and magnetostatic wave devices magnetic plate. Commonly used material has formed series, Ni series, Mg series, Li series, YlG series and BiCaV series ferrite material; and according to the need of single crystal devices made of amorphous, polycrystalline, or films, different structure and morphology. The characteristics of this kind of material is a magnetic trap in external mechanical deformation will be under the action of magnetic field, so it is also called magnetostrictive material, its function is to transform acoustic magnetic or magnetic energy. The vibration head, communication machine used in the ultrasonic generator mechanical filter and electric pulse signal delay lines, and microwave technology can produce micro acoustic magnetic plate. Due to the mechanical strength of alloy material, anti vibration and not burst, the vibration head for Ni series and NiCo series alloy; use for Ni series and NiCo series of ferrite in the small signal. The emergence of new amorphous alloy have forced magnetic variety, suitable for wire delay in production. Production and application of piezomagnetic material than in front of four kinds of materials.
