This is disc magnet is made of sintered ceramic ferrite, belongs to permanent magnet. The specific size is 8mm in diameter, 3mm in thickness. The grade is Y30BH, its surface magnetic strength around 1080 gauss, pull force is about 0.11kg. Although the magnetic force of ferrite is not as much as that of neodymium magnets, it is enough for many products, so it is often widely used. Round ferrite magnet is widely used in all kinds of packaging, leather goods, handbags, refrigerator magnets, toys, crafts, etc.
