Paper, 'On the magnetisation of iron in strong fields' by J A [James Alfred] Ewing and William Low

Description

Ewing and Low write: 'The behaviour of iron and steel when subjected to very strong magnetising forces is a matter of considerable practical and very great theoretical interest, especially from its bearing on the molecular theory of magnetisation, which assigns an upper limit to the intensity of magnetism that a piece of iron can acquire, and even suggests that the metal may become diamagnetic under the influence of a sufficiently great force. All experiments hitherto made, by magnetising iron in the field of an electric solenoid, have shown that the intensity of magnetism, as well as the induction, is increasing with the highest values actually given to the magnetising force.'

Annotations in pencil and ink. Includes three pages of diagrams of experimental apparatus and results.
