The magnetic force of big magnets is very terrible, and the price is relatively expensive. They are also called death magnets. They can be made into round, circular, arc, block and other shapes. If you need, our company can process and customize large neodymium magnets of about 100-220mm(5 inch - 8 inch) for you (or choose ceramic ferrite material). You just need to tell us the specific size of the magnet, and look forward to your inquiry!

Neodymium magnet still offers the strongest magnetic power nowadays and has been widely served to vast kinds of application, include high-performance permanent motors, brushless DC motors, magnetic separators, magnetic resonance imaging (MRI), sensors,loudspeakers, consumer electronics, and green energy. The third generation of rare earth permanent magnet NdFeB is the most powerful permanent magnet in modern magnets. It not only has the characteristics of high remanence, high coercivity, high magnetic energy product, high performance-to-price ratio, but also is easy to be processed into various sizes. Now it has been widely applied in various fields. Especially suitable for the development of high-performance, miniaturized, lightweight alternative products....
