所有的物质都显示磁性,当然显示的强弱程度是不同的。物质的磁性来源于电子的运动,磁现象与电现象之间有着密切的联系。由于电子绕原子核轨道运动和自旋,都有磁效应而产生磁矩。若将物质放在外磁场中,凡其中电子自旋的磁矩方向与外磁场相反,这类物质叫反磁质。凡物质中电子自旋的磁矩方向与外磁场相同,这类物质叫顺磁质。
All substances show magnetism, of course, show the degree of strength is different. The magnetism of matter comes from the movement of electrons, and there is a close relationship between magnetic phenomena and electrical phenomena. Due to the electrons around the atomic orbit and spin, have a magnetic effect and produce a magnetic moment. If the material is placed in an external magnetic field, where the direction of the magnetic moment of the electron spin is opposite to that of the external magnetic field, this kind of material is called antimagnetism. Whereas the direction of the magnetic moment of the electron spin is the same as the external magnetic field, this kind of material is called paramagnetic material.
