Product Description

High Quality D76.2xd50.8X12.7mm N42 Neodymium Ring Magnet
Ring Magnets are widely used in such applications as holding, motors, consumer electronics, medical, sensors and speakers.  Due to the high magnetic strength of a Rare Earth Magnet, it has replaced other magnetic materials in order to make a design smaller but achieve the same result.  Neodymium ring magnets are used extensively in industries such as the jewelry, medical, automotive, aerospace and power generation applications.
