Can a single experiment disprove Special Relativity? This is exactly what happens in the phenomenon of rotational unipolar induction discovered by Faraday in 1832, a situation in which a wire co-moving with a magnet receives an induced voltage. It denies the need of relative motion between wire and magnet stipulated by Einstein in 1905. Alternative relativistic views, however, propose that the induction occurs not in the co-moving wire but in the rest of the circuit, a highly debatable point. Some relativists even say that General Relativity is needed to solve the problem.
In 1988 I completed a series of experiments, substituting Faraday?s rotating disk and magnet by a filamentary circuit, one portion of which is immersed in a magnetic field (inside a gap between ceramic magnets) while the other remains outside the magnetic field. (The field is confined within iron plates as shown in the figure). By introducing a capacitive branch I could demonstrate that the induction occurs, indeed, in the wire that moves with the magnet, without need of relative motion. A variation of the experiment in rectilinear fashion makes this anti-relativistic conclusion totally unavoidable, invalidating the recourse to General Relativity. Important astrophysical consequences follow.
