Learn more about the classification and use magnets

Magnet is a very wide range of useful items that can be used in stereo , electrical , magnetic , packaging , electronic equipment, and many other uses.

Classification magnet , according to the raw material of able to hard ferrite, NdFeB, samarium cobalt magnets , alnico magnets, ferrite during simple inexpensive but fragile , small magnetic NdFeB magnetic , prices than iron oxide height , small samarium cobalt magnetic , usually on the instrument , Alnico high temperature strong magnet can be made cylindrical , square , circle , tile , all kinds of special , is not really an information economy .

Below is a brief analysis we have done on the magnet is usually used on what goods? What use is it usually has :

10. Could do magnetic pillow, magnetic belt
11 can use a magnet made ​​of flour and other end separator can remove iron can exist ( this is called separator )
12 magnetized water can do to avoid boiler fouling
13 magnetized seeds can be used , the effect is to make the crops must add extent
14 Rock is not the same geological age tend to have different magnetic properties. Thus , changes in the earth's crust can be determined and changed the basis of the geological age of rocks magnetic adjuvant.
16. Magnetic beneficiation
17 magnetic data in the same military areas has been widely used . For example , the average mine might only touch the principle of mine blasting , and thus the effect is limited .

Not only can not attract a ndfeb magnets found gold, silver, copper and other metals, can not attract items like bricks . Western Han division we now recognize that a magnet can attract iron , but can not attract other items.
