Since 2002 , focus on manufacturing and supplying various kinds of bonded ferrite magnets

     

What essentially the difference between the magnets and iron?

The magnet is not iron. Iron theoretical concept is: carbon content in 2. 11% - - - - - - - 6. 69% of the iron carbon alloy. From the production process, the cost of iron magnet more low cost and magnet is one of the rare earth neodymium, the material is more expensive. In this sense, the magnet iron in addition, it is not have magnetic magnetite, its main composition is ferroferric oxide. There are many types of artificial magnet, strong magnetic is artificial neodymium magnets. It is a kind of permanent magnets ( Powerful magnet) ! Ndfeb strong magnet ( Glass magnet) Many people think that the magnet is iron, the following is the classification of the magnet, the hope can help you answer your question. The classification of the magnet too much, I said here is simple: magnetic material material basically has two kinds: the first is the permanent magnetic material ( Also called hard magnetic) : material itself has preserved the characteristics of the magnetic force is the second soft magnetic ( Also called electromagnet) : need outside power to produce magnetic flat is a magnet which said, we are generally refers to the permanent magnet permanent magnetic material has two categories: the first major categories are: alloy permanent magnet material including rare earth permanent magnet ( Ndfeb Nd2Fe14B) , samarium cobalt ( SmCo) , nickel and cobalt neodymium ( NdNiCO) The second major categories are: ferrite permanent magnet material ( Ferrite) According to the different production process can be divided into: sintered ferrite magnets and iron actually no difference essentially, everything points of paramagnetic inverse magnetic material magnetic material inside is divided into many small areas, each tiny area is called a magnetic domain, each domain has its own magnetic spacing ( That is, a tiny magnetic field) 。 In general, the various magnetic from the direction of the magnetic domain, the magnetic field offset each other, so the whole material foreign is not magnetic. When the direction of the magnetic domain consistent foreign just shows the magnetic material. Magnet size: ndfeb magnets, samarium cobalt magnet, alnico magnets, ferrite magnets, ferrite magnets and iron have so a Mimi relationship, or the smallest. Magnet company is the specialized production ( Ndfeb) Powerful magnet company, has factories in dongguan city based wangniudun pier town.
