Neodymium Ring Magnet are great for loudspeaker, home theater, multimedia, headset, water meter, vibration motor, etc.
Sintered NdFeB Magnet Ring are supplied in different grades and sizes, maximum diameter 220mm, minimum thickness 1.0mm. Ring magnet, which are magnetized through thickness (axially), north pole and south pole are located on the top and bottom. Axially magnetized is common magnetism for ring magnets. Diameterically magnetized also can be made as per customer’s different requirement.
Neodymium magnets are the strongest, the most important and commonly used permanent magnets at present. Based on different manufacturing process, it is divided into sintered NdFeB magnets and bonded neodymium magnets. Neodymium Iron Boron Plate Magnets N38
HSMAG – China Rare Earth Magnet produce and supply both sintered and bonded NdFeB magnets in a variety of grades, sizes and shapes. Welcome to watch our YouTube video. We also supply some relevant products like magnetic pole detectors which can distinguish N, S poles of magnets, and digital gauss meter which can measure surface fields (Gauss value) of permanent magnet.

Sintered NdFeB magnets are stronger than bonded NdFeB magnets. The grade of sintered NdFeB magnets is named as N35~N52, N30M~N50M, N30H~N48H, N30SH~N45SH, N28UH~N40UH, N28EH~N38EH and N28AH~N35AH(Download Magnetic Property Sheet of sintered NdFeB).Under the temperature of 80°C,N52 magnets are the strongest permanent magnet material. Customers or users can order the most suitable NdFeB magnets from us according to their actual needs and application. Neodymium Iron Boron Plate Magnets N38
