Last Friday, a customer came to us and asked us if we could make a small bonded magnetic ring with an outer diameter of only 2.8mm and an inner hole of 1.45mm. The magnetization method in the technical requirements of the drawing is to position a pair of radial pole magnetization. What does this mean? The following magnet manufacturers Courage xiaofu on this to a simple explanation.
The following figure is a drawing of bonded Ndfeb magnet with a pair poles magnetizing in radial direction

First of all, positioning, is a requirement for magnet magnetization, such as all along the diagonal magnetization, fixed parts fixed magnetic poles, general products have such requirements, a pair of radial poles is relatively good to understand, a pair of poles is 2 poles, that is, radial 2 poles magnetization.
The above is an introduction to magnetization of a pair of poles in the radial direction of the magnet positioning, More articles: https://www.dgcourage.com/xinwen/hyxw/
