This is a large diameter flat countersunk magnet with an outer diameter of 100mm, a thickness of 3mm, and a pore size of 10mm. It can also be called a 100mm magnetic ring magnet with nickel plating protection on the surface. The highest surface magnetic strength measured with a Japanese Gauss meter is around 1900 Gauss, and samples can be processed according to your desired size, temperature resistance, and magnetic performance level.
