Neodymium ring magnets are being designed into a new generation of motors, generators, hydraulic cylinders, pumps & sensors. They also remain popular in high-end loudspeakers & high-intensity separators.Neodymium ring magnets are disc magnets or cylinder magnets with a plain hole through the center of the magnet. A ring magnet comes in many diameters. Neodymium (Neo or NdFeB) magnets are permanent magnets, and part of the rare-earth magnet family. Neo magnets have the highest magnetic properties and are the most powerful commercially available magnets today. Because of their magnetic strength, neodymium ring magnets are the preferred choice for many consumer, commercial and technical applications. Honsen Magnetics is specialized in manufacturing and supplying neodymium ring magnets applied in various industrial applications.Product Name: Permanent Neodymium Ring Magnet Material: Neodymium Magnets / Rare Earth Magnets Dimension: Standard or customized Coating: Silver, Gold, Zinc, Nickel, Ni-Cu-Ni.
