Book excerpt: Excerpt from The Influence of Frequency Upon the Self-Inductance of Coils Hence, it is evident that however the frequency of oscillation may change, the mutual inductance between pairs of wires remains absolutely unchanged, while any change which does occur is due to that of the terms involving self-inductance only. This difference is therefore n times the difference between the mutual inductance of two circular filaments when placed at a dis tance apart equal to X radius of the cross section of the wire used, and when placed at a distance apart equal to the radius. For these are the factors used in computing the self-inductance of a turn for low and high frequencies, respectively. Thus, it is easily seen that since in the last case the self-inductance is less than in the first the in uence of rapidly oscillating currents is to diminish the coefficient of self-inductance.
