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 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 it will be magnetized to the substance of the relationship between the structure of mechanical problems with magnets offer, and material 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, the magnet field lines do work itself, 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 sell machinery magnet, does not mean no loss. Without loss of mechanical magnets, electromagnets would not not consume point? 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 a magnet to attract high-quality machine with a magnet, remove the iron acting process requires external energy or conservation. Perpetual motion machine is impossible. Powerful magnet is how to make out I believe we all know the magnet, but the magnet has a lot of classification, especially NdFeB magnets, NdFeB magnets are wondering how to make out of it? What it has its way, let the new Tong Xin magnetic Limited's look: NdFeB magnet manufacturers need first to understand that it is necessary to contain alloy materials pulverized into particles, forming these particles come together, and then sintered. After then cut to the desired size to complete. Of course, in the actual production of high-quality NdFeB magnets is not so simple. Not only to unify the 3 ~ 5μm particle size, but also pay attention to the uniformity of shape, but also consider the method of heating during sintering and so on, it takes a lot of work to make. "Through massive accumulation of small technology, to reach a practical level it is today" (engaged in the development of the art neodymium magnets). For example, the alloy crushed to 3 ~ 5μm after implementation of the "magnetic field forming process" is one of them. This step is to fine powder (micro magnet) crushed orientation. NdFeB magnet manufacturers say here is the orientation of the magnetization direction of the powder of unity for a fixed direction and orientation, the higher the residual magnetic flux density (magnetic field strength index) will be. Carrying out the first step of the fine powder is filled into a mold, applying a strong magnetic field to orient powder, press molding processing is then performed. Which is unique in that the molded body will not collapse to the extent that the gentle pressure molding. Because the pressure is too great, then it will upset the hard-won unity of powder orientation. Mechanical much money magnet, machinery magnet magnetic new Xin Tong provided by the Dongguan City, Tong Xin magnetic Limited.
