磁称法原理附录:磁称法原理磁称法对弱磁性的测量在原理上归结为测量弱磁性物质在不均匀磁场中所受的力。置于不均匀磁场中的样品所受的力与磁化系数x之间的关系可以由以下分析得到。在磁场中被磁化物体的位能为
Principles of Magnetometry Appendix: Principles of Magnetometry Magnetometry The measurement of weak magnetism is in principle attributed to the measurement of weak magnetic material in a non-uniform magnetic field. The relationship between the force of the sample placed in an inhomogeneous magnetic field and the magnetization coefficient x can be obtained from the following analysis. The potential energy of a magnetized object in a magnetic field is
