 Martin Tajmar and his graduate student Fiedler characterized and attempted to quantify possible sources of error in their experiment at Dresden University of Technology.They ran multiple tests on their experimental setup, including measurements of the force along different axes with respect to the power supply current.While eliminating or accounting for many other sources of error in previous experiments, such as replacing a magnetic damping mechanism with an oil damper, less efficient but significantly less interacting with electromagnetic field, the study remained inconclusive as to the effects of electromagnetic interaction with the apparatus' power feed, at the same time noting it as possibly the most significant source of noise.
