Abstract:

In the magnetic susceptibility measurement experiment, the traditional method is to use the Gouy magnetic balance, an instrument which is cumbersome and complicated to operate. This paper provides a new type of benchtop magnetic balance for the determination of the magnetic susceptibility of complexes. The basic principle, method, operation steps and data analysis of this magnetic balance are introduced by measuring the magnetic susceptibility of three commonly used complexes. By comparing the measured values with standards, it is apparent that this portable instrument has smaller measurement error and higher precision, which is suitable for experimental teaching and scientific research.

Key words: Magnetic balance, Magnetic susceptibility, Improvement of the experiment
