A noninvasive method and apparatus for treating living tissue with pulsed electromagnetic fields (PEMFs) having selectively reduced high-frequency signal components, with improved bioresponse provided by magnetic field amplitudes less than approximately 40 T, and most preferably in the range of 4-10 T. Such amplitude levels for the disclosed PEMF signal are particularly effective with a treatment duration in the range of 0.25-2 hours/day.
