Passive Shielding of Magnetic Field in Transcranial Magnetic Stimulation – Outline of the Problem

During transcranial magnetic stimulation (TMS) sessions, under protection should be both operators of medical tools and patients. The aim of the paper is to estimate how a copper plate influences magnetic flux density with human thorax and abdomen. Magnetic flux density in low frequency band is reported to be difficult to be shielded completely. As presented in the article, shielding using even a simple method, contributes to a significant mitigation of magnetic field in certain area.
