This article presents the impact of fixed tissue conductivities on the distribution of eddy currents in human body. Electrical conductivities characterising human tissues present in limbs have been collated based on various publications from the last 25 years. The article shows the extent to which simulation results are affected by changes to electrical conductivity of specific tissues. It has been demonstrated that the tissues taking the largest part of the studied domain have the greatest impact. The conclusions from these results suggest that it is very important to determine the electrical conductivity of tissues forming the human body with increasing precision, as it is an important factor affecting the accuracy of results. This factor seems much more significant than the growth in the precision of models resulting from increasing resolution of numerical models made available for research purposes.
