The present invention is directed to an apparatus for influencing biological processes in living tissue, in particular human body, for applying a pulsating magnetic field to at least some of the tissue, having a field production apparatus (2) for producing the pulsating magnetic field and a pulse generator (1) for actuating the field production apparatus (2), wherein the pulse generator (1) is embodied in such a way that the pulsating magnetic field consists of a sequence of main pulses (11), the pulse repetition rate of which lies between 0.01 and 1000 Hz, wherein the main pulses (11) are formed by a plurality of overlaid sub-pulses (13) (figure 1), wherein the main pulses (11) are overlaid by secondary pulses (12), wherein the secondary pulses (12) have a phase shift f in relation to the main pulses (11) of -0.5 >； f >； 0.5 and the phase shift f is not equal to 0.
