ABSTRACT

We propose a new electromagnetic test or breakdown at local Lorentz invariance. It is based essentially on the detection of a non zero force between a circular steady current and a charge, both at rest in the Earth frame. A preliminary experimental run gave a positive evidence for such an effect, which appears strongly dependent on the orientation of the circuit. Possible theoretical interpretations are briefly discussed.
