Permanent magnetic ferrite and ferrite magnets

Permanent magnetic ferrite and ferrite magnets, is what we usually see black small magnets. The composition of raw materials mainly with iron oxide, barium carbonate and strontium carbonate. After magnetization, the residual magnetic field intensity is high, and can keep the residual magnetic field for a long time. Usually used permanent magnet materials. For example: the speaker magnet. Soft magnetic ferrite is composed of ferric oxide and other metal oxide (one or more of the following For example, nickel oxide, zinc oxide, manganese oxide, magnesium oxide, oxide barium and strontium oxide, etc. ) Preparation of sintering. Call it soft magnetic, because when the magnetization field vanishes, very small or almost no residual magnetic field. Usually used for choke, or intermediate frequency transformer core. This is completely different and permanent magnetic ferrite. According to the principle of electromagnetic induction, can generate magnetic field, current use of strong magnetic field will be generally referred to as a powerful magnet magnetic material is magnetized magnetic materials, are actually several different things: the most common magnets, such as general speakers with magnets, ferrite magnets.
