This is a square ferrite magnet, because the length and width both in 40mm, so also called square ferrite magnet. The thickness is 10mm and is the direction of magnetizing. Its material is ceramic ferrite, which can oxidation and corrosion resistance, has high working temperature is reach 250℃. This magnet has a strong power, so you must be careful of your hand when you pick it up. The surface center strength is about 640 guass, the surface outer strength is about 1100 guass. Burnur powerful square flat magnets never lose their power. There is not coating and color is black. The tolerance of mold ferrite is that ±2% in length and width, ±0.1mm in thickness; the cutting ferrite is that ±0.5 in length and width, ±0.1mm in thickness.
