| Abstract: | The principle of the vibrating sample magnetometer is introduced and a vibrating sample magnetometer is made by ourselves using electromagnetic driving method.Using this apparatus,the permanent magnetism of the isotropic permanent Ba ferrite is measured.Compared with the results made by a commercial vibrating sample magnetometer,the error is less than 1%,so the apparatus could be used in the teaching of modern physics experiment. |
| Keywords: | vibrating sample magnetometer magnetic moment calibration magnetic hysteresis loop |
