Use a magnet in our modern society we have a lot of products are required to use the magnet, you can see the effect of this product in our modern society is a great magnet mold, brought a lot for our use convenience. We are very familiar with the magnet is a product of the magnet, which allows us to use to bring a lot of good ways, but we are now inseparable from our products is the use of magnets. There are a lot of products are moving in the direction of the development of modern society overall magnet classes, which allow us to have more and better use of development. And we are now also able to make our products better use. In a variety of magnetic materials, the amount of power is still the largest high permeability ferrite and ferrite. Switching power supply and appeared widely used, is a major change in the power sector. Switching power supply is mainly used in the past computers and telecommunications, and later expanded to TV, VCR, video integration machine, VCD, DVD, electronics and other office automation equipment and lighting. Oxygen iron magnet to adapt the switching power supply light, small, thin requirements, the need to increase the switching frequency. The production of switching power supply transformer Mn-Zn ferrite core material must have good magnetic properties at higher frequencies and larger magnetic flux density (Bs), the kind of material is called power ferrite.
