FIELD: electrical and radio engineering. SUBSTANCE: method used to control electric current induced in conductor placed in magnetic field for amplifying or reducing it directly in conductor involves regulation of longitudinal component of electron speed in this conductor. Moreover, additional component transversal relative to direction of magnetic induction and current is imparted to electron movement through energized conductor. This component is imparted either by reciprocation of conductor or by means of alternating magnetic field. EFFECT: facilitated procedure. 7 cl, 2 dwg
