The experiments which form the subject of this paper are designed, in the first place, to test the relation pointed out by Maxwell between Joule's discovery of the lengthening of iron in the direction of magnetisation, and Wiedemann's later researches into the twisting of iron under the influence of longitudinal and circular magnetisations, and, in the second place, to investigate the corresponding properties of nickel.
