Abstract :
In this work we present two dual finite element formulations to compute extremely low frequency (ELF) induced fields into the human body. This allows to estimate the numerical error, as well as rigorously bound the (global) co-energy. This method is herein applied to the classical case of the exposure to a homogeneous magnetic field, and to the field generated by an infinite wire.
