NdFeB magnet:
Permanent magnets are materials where the magnetic field is generated by the internal structure of the material itself. Inside atoms and crystals you have both electrons and the nucleus of the atom. Both the nucleus and the electrons themselves act like little magnets, like little spinning chunks of electric charge, and they have magnetic fields inherent in the particles themselves. There's also a magnetic field that's generated by the orbits of the electrons as they move about the nucleus. So the magnetic fields of permanent magnets are the sums of the nuclear spins, the electron spins and the orbits of the electrons themselves. Permanent magnets are limited by the structure of the material. And the strongest magnetic field of a permanent magnet is about 8,000 gauss. The strongest magnets here at the Magnet Lab are 450,000 gauss, which would be almost 50 times stronger than that.
Widely Applications of neodymium magnets:
You can find small permanent magnets in toys, handheld gadgets such as electric razors, and clasps for bracelets and watches. Larger permanent magnets are useful in household appliance motors and in stereo speakers. The electric motors in hybrid vehicles use very strong permanent magnets.
Customized Service
1. Customized Material Neodymium Grade: N35-N52, N35M-N50M, N35H-N48H, N33SH-N45SH, N30UH-N35UH, N30EH-N35EH;
2. Customized Shaped magnet: Round / block / ring / cylinder / countersunk / arc / segment other irregular shapes.
3. Custom packaging. Usually we packed the magnet with vacuum polybag. Then packed in stop magnetic metal box. We can also make the package as your requirements.
4. Customized Mark: to distinguish N pole and S pole.
5. Custom coating. We can coated in Nickel. Zinc, Chromium as your requirements.
6. Customized Working temperature: 80℃-200℃
Grades of Neodymium
N35, N38, N42, N38SH...what does it all mean? Neodymium magnets are all graded by the material they are made of. As a very general rule, the higher the grade (the number following the 'N'), the stronger the magnet. The highest grade of neodymium magnet currently available is N52. Any letter following the grade refers to the temperature rating of the magnet. If there are no letters following the grade, then the magnet is standard temperature neodymium. The temperature ratings are standard (no designation) - M - H - SH - UH - EH. You find the temperature rating of each grade on our Specifications of Neodymium Magnets Page
Our Advantages
We are a small business that has been a long time in the making. We have worked for both large and small businesses over the years, where we have learned a lot about business - both what to do - and what not to do.
