TitlePaper, 'On the production of transient electric currents in iron and steel conductors by twisting them when magnetised or by magnetising them when twisted' by J A [James Alfred] Ewing
Date16 July 1881
DescriptionEwing observes that an iron or steel wire subjected to longitudinal magnetisation by a surrounding solenoid gave, when twisted, a current along itself, which was observed by means of a ballistic mirror galvanometer in circuit with the wire. When the twist was that of a common screw the transient current flowed along the wire from the nominal north pole to the nominal south pole. An opposite twist gave an oppositely directed current.
