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.
