The Magnetic Permeability of Iron Wires at Radiofrequencies

摘要

The magnetic permeability of iron wires of selected diameters is measured at fields of low intensity and at frequencies corresponding to wave‐lengths from 54 to 1150 meters. The observed permeabilities decrease with increase in frequency and increase of wire size. The results do not confirm the existence of an anomalous dispersion of permeability previously reported by some investigators.
