The acceleration of an electric conductor is predicted to produce an electric field proportional to m/q where m is the free mass and q the charge of the carriers of the electric current. In certain configurations this leads to a measurable EMF. In this paper we report a measurement of the EMF produced by rotationally accelerating coils of aluminium and copper wire. This experiment essentially repeats, using modern instrumentation, the 1916 Tolman - Stewart experiment. The measured EMFs are found to agree with theory to better than 1%.
