What the magnet magnetic is one of the biggest? This is called a powerful magnet, it is very intuitive, powerful magnets, is refers to the ndfeb magnet. It compared with the ferrite magnets, alnico, samarium cobalt magnetism can greatly over several other magnets, because it can adsorption weight that is hundreds of times greater than themselves, so everyone called powerful magnets, the magnetic is the largest of the magnet. A strong magnet in the application of nuclear magnetic resonance (NMR) imaging industry. Nuclear magnetic resonance (NMR) imaging is the application of new technology and new equipment in the 80 s, he can organizations at various angles photos inside human body, thus can constitute a three-dimensional image, determine the nature of the lesion and form, to determine the initial tumor lesion is very helpful. The past is to use superconducting magnet, the disadvantage is that cost is high, the high cost of operation. If done with permanent magnet ferrite, a magnetic resonance imaging (mri) apparatus to permanent magnetic ferrite, 100 tons, but if use ndfeb magnets, each only 0. 5 tons, if in the future market demand in 10000, around the world need ndfeb magnet 5000 tons. Soft magnetic material physical characteristics are: 1, the residual magnetic induction intensity of Br. 2, rectangular than; 3, permeability & mu; ; 4, Curie temperature Tc; 5, loss P 1, first, in accordance with the request of circuit concluded that voltage and current characteristics of equipment. Equipment of the voltage and current characteristics closely related to how much shape and magnetization of magnetic core status. Planners need to know information of magnetization process and hold data of magnetic parameters and equipment of electrical parameters of transformation. Planning soft magnetic equipment usually includes three processes: accurate selection of magnetic material; Reasonable to conclude that how much shape and measure of core; On the basis of magnetic parameters of the request, imitate the operation conditions of magnetic core corresponding electrical parameters. 2, soft magnetic materials commonly used magnetic parameters of the saturated magnetic induction intensity of Bs: its size depends on the material composition, it corresponds to the physical state of magnetization vector lined up inside the material. Tip: magnet manufacturer magnet in use process shall ensure that the workplace is clean, prevent iron filings and other minor impurities adsorption in magnet appearance affect the normal use of the goods. Magnet, powerful magnets, special-shaped magnets, magnet manufacturer,
