A thermo magnetic analysis (TMA) apparatus is used to follow reactions under controlled conditions of temperature and pressure with the Faraday method. Relations giving the conversion degree λχ at a given timet as a function of the sample susceptibility are presented. Methods for studying the effects of the magnetic field on the reaction kinetics are considered. In particular, the kinetic curves obtained for the reaction
