The paper deals with the current density distributions in toroidal conductors of circular cross‐section.


A review of the analytical solutions existing in the literature only for the case of very thin skin depth is presented.


Results are given for different aspect ratios of torus. The accuracy of these analytical solutions is verified by comparison with numerical results. Finally, a set of numerical results are given for the same aspect ratios but different penetration depths of the electromagnetic wave in the conducting material.


The paper provides results for different penetration depths of electromagnetic wave in conducting material and different torus aspect ratios.
