Abstract: | The physical properties of the vector potential were considered in terms of the problem of bioactivity of electromagnetic fields. A possible primary mechanism underlying the effect of vector potentials on elementary processes of charge transport were considered by analogy with the well-known Aharonov-Bohms and Josephsons effects. The possibility of using the curl-free vector potential for "force-free" information effect on biochemical processes in the living cell was grounded. The technical possibilities of creation of vector potential free of magnetic field in laboratory are discussed. |
