A magnetic field therapy apparatus includes a magnetic field generation device for generating a magnetic field that can be applied to a patient, and a control device for controlling an intensity of the magnetic field in such a way that the magnetic field intensity increases incrementally during a first interval T1 and is set to a constant level during a second interval (T2), the ratio of the first interval T1 to the second interval T2 corresponding to the golden section +/−0.1, preferably +/−0.01.
