Abstract

A Gray-Ross magnetometer was used to obtain I-H curves for a steel rod under normal conditions and under the influence of arotating magnetic field to find whether the effect of the latter would he to help in the process of producing longitudinal magnetisation of the rod. The rotation of a bar-magnet in a plane at right angles to the axis of the specimen, and near to the magnetising solenoid, was used to supply this field, which was therefore not very strong and decreased towards the end of the specimen distant from the rotating magnet. When the I-H curves for a given range, and under the different conditions, were compared, the curve obtained for either direction of rotation of the magnet differed but slightly from the curve for normal conditions. Sometimes it seemed that the rotating field helped, but in other experiments the opposite was indicated, and in other sets no difference was distinguishable, so it was concluded that a rotating magnetic field of the order used has no distinct effect on the longitudinal magnetisation of a specimen lying in the direction of the axis of rotation.
