Rotating coils constitute a type of electrical transformers used to produce alternating voltage pulses exploiting the phenomenon of electromagnetic induction. In this study, we investigate the influence of the electromagnetic scattering from a metallic obstacle located inside the moving component. In particular, a perfectly conducting spherical core is positioned eccentrically inside a thin circular ring, rotating around an arbitrary axis passing through its own center, under plane wave excitation. Methods and formulas implemented in scattering and induction problems have been utilized for the derivation of the developed potential difference around the loop. Several graphs of the voltage output versus the geometrical characteristics of the configuration, are shown and explained
