Calculation formula of ndfeb manufacturers: * = square square magnet weight volume density of ndfeb magnet volume: the volume of a cube is fixed, is three level multiplication ndfeb magnet density: 7. 5 g/cm after example: N3530mm * 15 mm * 6 mm square magnet volume: 30 * 15 * 6 density: 7. 5 g/cm after weight = 30 * 15 * 6 * 0. 0075 = 20. 25克( G) The size of the ndfeb magnet mm in general ( 毫米) As the unit. Can be calculated directly set on the formula. If it is cm ( cm) Need to transform. 1厘米= 10毫米。 。
