Quasistatic transient electromagnetic response of a permeable nonuniformly conducting cylinder
Abstract
The step-pulse response of a permeable and a radially nonuniformly conducting cylinder is obtained. Effects of the conductivity distribution pattern and the magnetic permeability on the transient response are examined in detail. It is found that: (1) the initial response remains unaffected by both the inhomogeneity and the permeability of the cylinder; (2) the large time response is governed only by the permeability; and (3) the conductivity inhomogeneity is reflected only during intermediate times. Implications of the results for predicting the parameters of the cylinder are discussed.
