  We have implemented field models and performed a detailed numerical dosimetry
inside our extremely-low-frequency electromagnetic bioreactor which has been
successfully used in $\textit{in vitro}$ Biotechnology and Tissue Engineering
researches. The numerical dosimetry permitted to map the magnetic induction
field (maximum module equal to about 3.3 mT) and to discuss its biological
effects in terms of induced electric currents and induced mechanical forces
(compression and traction). So, in the frame of the
tensegrity-mechanotransduction theory of Ingber, the study of these
electromagnetically induced mechanical forces could be, in our opinion, a
powerful tool to understand some effects of the electromagnetic stimulation
whose mechanisms remain still elusive.
