Abstract

DURING the course of an investigation of the variation of the longitudinal incremental permeability by a superimposed circular magnetic field, some rather interesting results Were obtained with certain iron-nickel alloys. The ferromagnetic materials under investigation were of wire form and served as the core of a long slender solenoid. Direct current was passed through the core to produce the circular field, and the longitudinal permeability was calculated from inductance measurements on the solenoid.
