The invention concerns an apparatus to apply an electromagnetic field on at least a part of the body including at least a transducer and a generator to apply an ac signal on the transducer, whereby the transducer is adapted to generate to apply on at least a part of the body at least a part of the by the transducer generated electromagnetic field, wherein the generator is adapted to generate an ac signal with a basic frequency situated between 0.1Hz and 4000Hz. The basic idea of the invention is the acceptance according to which an applied electromagnetic field with the preceding described properties, applied on the body modulates the immune system of that body. This modulating effect on the body is due to the fact that magnetic fields with low frequencies and a small amplitude, like mentioned above, generate or induce small potential differences in the tissues. These small potential differences and their effects seem to have a stimulating or modulating effect on the cells belonging to the immune system.
