|Title||Locality and Electromagnetic Momentum in Critical Tests of Special Relativity|
|Keywords||Locality, Electromagnetic Momentum, Special Relativity|
In this review of recent tests of special relativity it is shown that the electromagnetic momentum plays a relevant role in various areas of classical and quantum physics. Crucial tests on the locality of Faraday's law for ?open? currents, on a modifed Trouton-Noble experiment, on nonconservation of mechanical angular momentum, on the force on the magnetic dipole, and on a reciprocal Rowland.s experiment are outlined. Electromagnetic momentum provides a link also between quantum non local effects and light propagation in moving media. Since light waves in moving media behave as matter waves in nonlocal quantum effects, the flow of the medium does affect the phase velocity of light, but not necessarily the momentum of photons. Thus, Fizeau's experiment is not suitable for testing the addition of velocities of special relativity. A crucial, non-interferometric experiment for the speed of photons in moving media, is described.
