An efficient numerical source model is proposed to calculate the induced current densities in the human body from measured low‐frequency inhomogeneous magnetic fields emitted by electronic devices (e.g., household appliances or power tools). Due to the complex geometrical structure and complicated construction of the devices, an efficient equivalent‐source formulation using magnetic elementary dipoles is determined to characterize the field source. Consequently, the validity of the proposed equivalent‐source model is confirmed, and the induced current density in the human body is calculated for several kinds of appliances. © 2001 John Wiley & Sons, Inc.
