磁体磁化率绝对测量技术(在法拉第以后命名的),研究人员已经使用很多年了。从理论上说是很简单的。将质量为 m 的样品放在磁场 H、磁场梯度 dH/dz 中,它的轴向力 Fz 为:Fz=mψH(dH/dz)这里的ψ是物质的磁化系数最近几年由于两方面原因使这种测量方
The absolute measurement of magnet susceptibility (named after Faraday) has been used by researchers for many years. In theory is very simple. The sample of mass m is placed in a magnetic field H, magnetic field gradient dH / dz, its axial force Fz is: Fz = mψH (dH / dz) where ψ is the material’s magnetization coefficient in recent years due to two reasons This measurement side
