Abstract
Electromagnetic scattering and electromagnetic induction are research topics not directly associated to each other. In this work, these two different concepts are combined in a model constituted by a rotating circular coil with a dielectric spherical core at a fixed eccentric position. The scope of the analysis is to examine the effect of a permeable object on the production of the alternating voltage. Methods and formulas from both scattering and induction have been utilized for the derivation of the developed potential difference around the moving loop. Several graphs of the voltage output with respect to the geometrical and material characteristics of the configuration, are presented and discussed.
