This is miniature 2mm cylinder neodymium magnet, that means the material is rare earth neodymium, the specific size is 2mm in diameter, 6mm in thickness. This tiny size we also can make other shaped, like round, ring, rectangle, square or other special shaped by your equirment. This magnet has a strong power that is 3590 gauss about surface magnetic strength. The direction of magnetizing is axial(also called thickness), but youcan choose radially magnetizing. If you want a neodymium magnet can work at 200℃, you can choose the grade end with EH(200℃) or AH(230℃).
