Abstract
The torque experienced by a current loop, of magnetic momentm, and moving with velocityv in an electric fieldE, cannot be explained in terms of the interaction between the loop current andE, but only by taking into account the internal stress in the loop. This subtle effect can be tested by measuring the frequency changes in the Zeeman splitting of moving atoms, the change of helicity of elementary particles, and the current induced in a moving coil. These tests may have relevance in the context of modern ether theories and of the Aharonov-Casher effect.
