Numerical modelling of magnetic stimulation in the spine is a scarce subject in the literature, although it has been gaining clinical acceptance. In the present work we present the results from a simplified computational model of the spine. The results indicate that it is necessary to use a numerical technique for solving the problem, which takes into account tissue dispersion and both dielectric properties (conductivity and permittivity), since a difference of 14% in the induced electric fields was found when displacement currents were included. With respect to the role of tissues in stimulation efficiency, it was confirmed that water-rich tissues lead to a shielding effect of the spinal cord. However, this effect becomes smaller at the height of the intervertebral discs, resulting in an increase of the field inside the spine.
