The sample is a black magnetic ring, the material is bonded neodymium, also belongs to a kind of neodymium iron boron, has a strong magnetic induction strength, the magnetic ring has 12 poles, 6 N poles and 6 S poles in the inner diameter surface of the magnetic ring, the specific dimensions of the outer diameter of 28mm, the inner hole of 24mm, the height of 10mm, the apparent magnetic strength of 2600 gauss or so, suitable for permanent magnet DC motors, robots, power tools, office equipment, etc., welcome to inquire about the off-the-shelf or close to the bonded neodymium iron boron ring magnets.
Inner diameter 12 poles magnetized ring neodymium magnets 28x24x10mm
Close to size multi-pole magnetic rings are recommended;
4 pole bonded NdFeB ring magnetized by inner diameter 28x24.8x8.5mm
Multi-pole magnetic ring knowledge science;
Is the number of magnetizing poles of a magnet unlimited?
