This is a semi-circular neodymium magnet made of rare earth neodymium material. It has a standard semi-circular diameter, equivalent to cutting a circular magnet into two halves. It has a diameter of 25.4 mm and a thickness of 3 mm. Its special feature is its magnetization direction, which uses radial magnetization, resulting in strong magnetic properties on the sides. It is more suitable for use in circular combinations, magnetic ring assemblies, or special sensor applications.
