Abstract : The complexity of the models used in validation studies over the last few years has increased. Complexity has been included in the probe operation, the core/coil shape, the inclusion of ferrite cores, and the inclusion of dimension and orientation variation. An issue with these validation studies is there is no quantitative understanding of how a small change in a parameter affects the probe response. This study will look at the variation of probe response over a range of variations in multiple orientations. In addition, a sensitivity study will be performed to determine which orientations produce the greatest variations in response and if there are parameter levels where the response is more affected by the variation.
