ABSTRACT:
An inductor having an air gap in its magnetic core is provided with a magnetic shield which surrounds the inductor air gap to not only reverse bias the inductor magnetic circuit so as to increase the amount of current required to achieve inductor saturation but also to return any stray flux radiating from the inductor back into the inductor magnetic circuit to reduce the radiated electromagnetic interference.
