A device for influencing biological sequences in living tissue, in particular a human body, includes a field generation device for generating the pulsating magnetic field to be applied to at least a part of the tissue, and a pulse generator controlling the field generation device. The pulsating magnetic field is composed of a sequence of primary pulses which are formed by a plurality of superimposed sub-pulses, the pulse repetition rate of which is between 0.01 and 1000 Hz. The sequence of primary pulses separated is from a second sequence of primary pulses by a rest phase. The curve profile of the maximum amplitude of the primary pulses has a slope mB of −∞ mE>0.1 at the end of the rest phase.
