Product Name: Rare Earth Neodymium Magnet Manufacturer Model NO.: N35-N48 Coating: Nickel Application: Industrial Magnet Shape: Block Type: Permanent Composition: Neodymium Magnet Trademark: Yuxiang Transport Package: Neutral Paper Carton Packing Specification: ROHS, SGS, CE Origin: China HS Code: 85051110 Product Description Rare Earth Neodymium Magnet1. Rare earth neodymium magnets are very strong magnets, they are high resistance to demagnetization and are very useful in many different kinds of industrial applications. NdFeB energy grade upto N52 magnets. Besides, we can also supply many other grades, like N50 magnets, N42 magnets, N40, N30 etc.2. Our neodymium magnets are particularly suitable for high volume production of awide variety of shapes and size ranges. Precise dimensional control is achieved in both processed and usually the component does not require further machining3. Neodymium magnets are very strong relative to their mass, but are also mechanically fragile. The neodymium magnets we sell are extremely strong, and must be handled with care to avoid personal injury and damage to the magnets. Fingers and other body parts can get severely pinched between two attracting magnets4. Injection moulded neodymium iron boron magnets do not normally require coating due to better corrosion resistance, however coating is recommended for compression moulded NdFeB5. Neodymium magnets are now being used in the music industry. Some manufacturers are using them as speaker magnets due to their strong magnetic field, stability, and weight. This makes for equipment that is lighter and more portable.There are 4different ways in which you can identify the poles of Neodymium magnets.1. The simplest way is to use another Neodymium magnet that is already marked. By virtue of magnetic properties, the North Pole of the marked magnet will attract the South Pole of the unmarked Neodymium magnet and repel the North Pole2. Take acompass and bring it close to the Neodymium magnet you want to mark. The North Pole of the compass will be attracted to the South Pole of the Neodymium magnet and repelled by the North Pole3. Take amagnet and dangle it by astring so that it is freely rotating. The North Pole of the magnet will be the one that points north4. Use our magnetic pole detector, which is also in the range of our products, to identy the pole of magnet easily.For more detail info, please feel free to visit our website or inquire us at any of your convenience.Ying JunSenior technical manager Yuxiang Magnetic Materials Ind.
