 NdFeB magnets are the advantages of cost-effective, with good mechanical properties; The disadvantage is that the low point of the Curie temperature, the temperature characteristics are poor, and easy chalking corrosion, so it must be adjusted to take its chemical composition and surface treatment methods Improved pin magnets, in order to achieve the requirements of practical applications. NdFeB rare earth permanent magnet material belongs to the third generation, with a small size, light weight and strong magnetic features special magnet assembly line, is currently the best price-performance magnets, the magnetic circles known as Magneto. The advantages of high energy density make NdFeB been widely used in modern industrial and electronic technology. In the state of bare magnetic, magnetic reach about 3500 gauss. After the magnet itself is magnetic magnet manufacturers will weaken It is understood magnetic magnets will not lose. When the magnetized iron, electric iron molecules aligned along the magnetic field, the magnetic field will in turn strengthen the formation of iron magnetic magnets, removed the magnet , iron molecules retain some of the magnetization direction of the electric field. And this process is our staff put the two together, and people do work. Electromagnet not the same situation, do not ferromagnetic material of the electromagnet will restore the original state after a power failure, the magnetization direction is not retained. If you use a non-ferromagnetic material near the magnet, the same can not be magnetized. As will be related to the magnetization, this issue is related to the structure of matter, and matter inside the depolarization field size. After said ferromagnetic magnet manufacturers of original magnet magnetic losses. The main magnet with its own magnetic field lines of the iron molecules arranged in neat rows, magnetic field lines do their own power, so to lose some. Can be calculated. This function is very small, generally ignored. In addition, the movement of the magnet, but also produce iron induced current, transformed into a counter electromotive force and returned to the counter-current magnet part into heat, lost. Less loss, does not mean there is no loss. If you do not lose, do not consume it not electromagnet point? Perpetual motion does not have hope? When the iron close to the magnet is magnetized iron can indeed increase the magnetic field, but the iron in a magnetic field and a negative magnetic potential energy E = - (magnetization vector) dot (magnetic induction), energy is conserved. Remove the iron magnet lock industry dedicated magnet, the magnetic potential energy disappears, the energy seems to increase the magnet is provided by the outside world really do work. Because iron is attracted magnets remove iron acting process requires external energy is conserved. Perpetual motion is impossible.
