Abstract

Describes the characteristics of external magnetic nearfields, computations of and requirements on induced electric fields in body tissues in the frequency range from 1 Hz to 6 MHz with respect to induced electric shock phenomena, for electroheating (EH) based treatment technologies and for electromagnetic processing of materials (EPM).
