For example, affected by the nuclear leakage accident in Japan, Germany will plan to abandon nuclear power to generate electricity completely. And the same time, strive to develop new & Renewable Energy, such as wind power and solar energy. Refer to wind power, magnet which plays important role in wind turbine generator to generate power cannot be ignored. At present, the magnet which used on wind turbine alternator is Sintered NdFeB magnet (Commonly known as magnet king, permanent magnet, rare earth magnet); The common grades are N42, N48, N50, and N38SH and so on; The common shapes are segment, block, wedge, and trapezoid; The coating is Ni-Cu-Ni triple plated The biggest block magnet for wind turbine generator is about 240x80x40 mm (the thickness cannot over 50mm) The normal block size is 2 (2 inches x 1 inch x 1 inch) China also develops wind energy rapidly these years. In 2011, there is half Wind Power Equipments for the whole world made in China. In this field, China is ahead of Germany and USA, and dominates the industry. This mainly depends on domestic magnet manufacture. Recently, considering high cost in purchasing wind turbine from China, many customers plan to purchase accessories and material and make wind turbine by themselves. Of course, this includes magnet purchase from China. China magnet source care customers benefit and will provide Wind Turbine Permanent Magnet with good quality, reasonable price; to satisfy customers requirement in making family-type or industrial wind turbine. 1.

Walking in a residential area, you will find people sitting on the road side with the billboard of home electric appliance recycling. Japanese is using the recycled aluminum, iron and other resources to build their own "urban mines". Compared with the country which only uses their nature resources, japanese is wiser. The magnetic separator is equipment used on recycling industry to distinguish the ferrous and non-ferrous, copper, aluminum and plastic. Their work mainly depends on the function of magnetic force and alternating magnetic field. There are hard magnet and soft magnet. The magnet used on separator is hard magnet. Hard magnet is classified into five categories: sintered ndfeb, bonded ndfeb, ferrite, samarium cobalt, alnico. Only strong magnetic force can separate metal and non-metal apart. According to this, separator magnet is generally sintered ndfeb. At the same time, to consider magnet cost, big block ferrite is also an option. Samarium cobalt, alnico, and bonded ndfeb are not strong enough on magnetic force and high cost, so don t in considering the scope. The shape of separator magnet is block. Like ferrite, the size is 6 . The size of sintered ndfeb depends on the design of magnetic equipment manufacturer. Every company will choose size and grade of permanent magnet according to their application. 1. To delivery by air or by express: anti-magnetic package (six sides iron sheets in the carton); 2.

Description : Plastic-bonded magnets are particle composites with permanent-magnet powder embedded in a plastic binder. Hard ferrite (HF), various SmCo and NdFeB powders and, to a very little extent, AINiCo alloys are used as magnetic powder. For embedding the magnetic particles, thermoplastic binders as, for instance, polyamide (PA) or polyphenyl sulfide (PPS) and duroplasts like epoxy resins are used. Depending on the material composition and production process, isotropic and anisotropic magnets with differing magnetic and mechanical specifications are available. Since not only the type of magnet or plastic material, but the filling and alignment degree, too, determine the composite`s properties, the outcome is widely varying magnetic parameters and an outstanding variety in types and shapes.
Halbach array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side.[1] This is achieved by having a spatially rotating pattern of magnetisation. The rotating pattern of permanent magnets (on the front face; on the left, up, right, down) can be continued indefinitely and have the same effect. The effect of this arrangement is roughly similar to many horseshoe magnets placed adjacent to each other, with similar poles touching.
