9. Q: magnet can be used in the water it? A: Depending on the material, not every magnet can be used in the water. Samarium cobalt ferrite magnets can be used normally packaging machinery in the water, NdFeB and Alnico not be used in the water. 10. Q: How adsorption measured? A: The suction force is determined according to the following method: the magnet side adsorbed on a piece of iron, a piece of the other side of the chest with a rubber on 5mm thick sheet iron crafts packaging magnets stick together, when the magnet and the iron plates The moment of tension is the suction force of the magnet. 11. Q: buy back the magnet can rework it? A: Because the mall is already an existing magnet magnetized products, no longer suitable for mechanical processing, such as the need special products please sent me drawings, we can be customized according to specific customer requirements. Permanent magnet permanent magnet may be a natural product gift packaging magnets, also known as lodestone, also be made artificially produced (the strongest magnets are NdFeB magnets) having a wide hysteresis loop, high coercivity, high remanence one that is able to maintain a constant magnetized magnetic material. Also known as permanent magnetic materials, hard magnetic materials. Application packaging magnet, a permanent magnet work in magnetic Switzerland and the depth of the magnetic saturation magnetization loops of the second quadrant demagnetization section. Permanent magnets should have as high a coercive force Hc, remanence Br and maximum energy product (BH) m, in order to ensure maximum magnetic energy storage and stable magnetic properties. Permanent magnets are widely used in electronic, electrical, mechanical, transportation, medical and household items and the like. Such as speakers, telephone receiver permanent magnets; Magnetoelectric meter magnetic system; generator pole permanent magnet motor; machinery used in manufacturing permanent magnet devices (such as a permanent magnet chuck surface grinder, etc.) and suspension system, magnetic bearings ; magnetic separation systems, magnetic beneficiation, magnetic water purification systems, magnetron, proton accelerator magnetic system. Packing magnet pieces, the new Xin Tong magnetic, packaging 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.
