The Gouy magnetic balance is characterized by its simple structure and high sensitivity. The magnetic susceptibility of paramagnetic substances was measured by the Gue magnetic balance method, and the number of unpaired electrons was estimated, and the type of bonding of these molecules was judged. Through experiments, we will master the experimental principle and technology of measuring the magnetic susceptibility of the Gue method, and understand the magnetization phenomenon of atoms, molecules or ions of matter under the action of external magnetic field. DP-FD-FM-A magnetic balance has the characteristics of compact structure, stable performance and convenient experiment. It is suitable for physical and chemical experiments and magnetic measurement research in colleges and universities. The instrument is mainly composed of electromagnet, constant current power supply, digital Tesla meter, etc. The following experiments can be completed by using this instrument:
