Abstract
This paper describes how powerful neodymium magnets and an electronic balance can be used to determine magnetic moments and susceptibilities of transition metal complexes. The technique is an improvement on one previously reported (J. Chem. Educ. 1998, 75, 61) and allows the effect of temperature on paramagnetism to be studied. Results consistent with the Curie law are reported and a theoretical background to the measurement of magnetic moments is given to explain why magnetic field strength and its gradient are important to the technique described.
Supplement
Some notes on background derivations, with relevant references, are available.
