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 sensitive to temperature change and even lose magnet properties at high temperature
Neodymium magnets lose -0.09 ~ -0.13% of Br/oC and can work stably under 80oC for low Hci Neodymium magnets and 150oC for high Hci Neodymium magnets.
Sintered rare earth NdFeB magnet: is one of the high performance rare earth permanent magnets, which use neodymium (Nd), iron (Fe), and boron (B) as their main ingredients
The NdFeB magnet has high remanence, high coercive force, high energy product and high ratio between performance value and product cost. Custom Made Magnet Neo Circular Ring N38UH OD 83mm
