After the magnet is magnetic data itself will be weakened without loss of magnet magnet magnetic manufacturers understand when the magnetized iron, iron molecules in an electric field aligned along the magnetic field, the magnetic field will in turn strengthen the formation of iron magnetic magnets, removed the magnet , iron molecules in the magnetization direction of the electric field there are some reservations. And this process is a magnet motor Which is good word of mouth is our staff put the two together, is the man to do the work. Electromagnet is 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 a non-ferromagnetic material near the magnet, the same can not be magnetized. As the motor will not be magnetized magnet, this relates to the question of the structure of matter, and matter inside the depolarization field size. After said ferromagnetic magnet manufacturers of original magnet magnetic losses. The main magnet field lines with their own iron molecules arranged in neat rows where the good motor magnets, magnetic field lines to do their own work, so to lose some. It can be calculated. This power is very small, generally neglected. In addition, moving magnet, iron should produce induced current, converted to the counter electromotive force and returned to the counter-current magnet portion is converted into heat, they lost. Less loss, does not mean no loss. If you do not lose, do not consume point electromagnet would not it? Perpetual motion machine does not have hope? When the iron close to the magnet is magnetized iron does increase the magnetic energy, but the iron in a magnetic field and a negative magnetic potential energy E = - (magnetization vector) dot (magnetic flux density), energy is conserved. Remove the iron magnet, the magnetic potential energy disappears, the energy seems to be increased, indeed supplied from outside acting. Because iron is attracted magnets remove iron acting process requires external energy or conservation. Perpetual motion machine is impossible. Magnetic force arranged: NdFeB magnets, samarium cobalt magnets, alnico magnets, ferrite magnets. Magnet production process: NdFeB magnets, samarium cobalt magnets, alnico magnets, ferrite magnet production process is also different. Speaking from the process, there are sintered NdFeB magnet and bonded NdFeB magnets, we mainly talk sintered NdFeB magnets. Process: ingot-melting ingredients → → → milling →-pressure sintering tempering → magnetic detection → grinding → pin Qiejia → plating → finished. Wherein the ingredients are based on the key performance sintering tempering tester, Gaussmeter. Which magnet motor, the new Xin Tong magnetic motor with a magnet provided by the Dongguan City, Tong Xin magnetic Limited. Dongguan City, Tong Xin magnetic Limited (www.dgxtxmagnet.com/) Dongguan, Guangdong, magnetic leader, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. New Tong Xin magnetic leadership with the staff warmly welcome all inquiries to discuss, with new magnetic Xin Tong better future.
