This study evaluated the gradient-induced heating of a pair of metallic plates (dimensions similar to commercial medical implantable pulse generators IPGs) made of different materials in order to determine a suitable test procedure for the test of gradient induced heating. From the obtained results, it is observed that a worst-case exposure cannot be concluded only by a particular set of gradient field conditions for all different implants.
