Product Description

1, Description for N40 Sintered NdFeB ring magnet widely used in speaker

Ring magnets can be magnetized in different ways. The most common way is through the thickness and most of these are magnetized that way. I can also request an shape neodymium ring magnet to be magnetized through the diameter. Neodymium cannot be magnetized radially - with a pole on the outside edge and the opposite pole on the inside edge. However, if you really need neodymium ring magnets to have a radial magnetization pattern we can make them in arc segments that you can put together. Note: placing all the arc segments so that all north poles point in the same direction means that they all repel each other and will have to be held in place - usually with epoxy or CA glue.
