Boldyreva boldyrev-m@yandex.ru 1 The State University of Management It is shown that using the inertia-free process of transferring angular momentum, which was introduced by Maxwell in the model of luminiferous ether, it is possible to explain many physical phenomena, most of them have had no physical explanation as yet. Such phenomena are, in particular: spin supercurrent supporting the ˇ°stiffnessˇ± of spin part of the order parameter in superfluid 3He-B; quantum correlations between any quantum entities of both zero rest mass (photons) and non-zero rest mass; the vector magnetic potential; the generation of energy in a rotating nonlinear magnetic field; the energy of cavity structures. The inertia-free process may spread at the speed higher than the speed of light and this does not contradict Special Relativity as the latter postulates the speed limit only for an inertial process; besides, the inertia-free process is not characterized by kinetic energy and does not take part in gravitational interactions. http://pubs.sciepub.com/ijp/9/2/3/ijp-9-2-3.pdf MaxwellˇŻs luminiferous ether inertia-free process spin supercurrent transfer of angular momentum spin
