Claim 11:
12. A magnetic field therapy system for treating cancer cells in a target body area of a patient, comprising:
an alternating polarity (AP) magnetic field generator;
one or more AP electromagnetic coils coupled to the AP magnetic field generator and adapted to be coupled to the target body area, wherein each AP electromagnetic coil may be energized by an electrical signal from the AP magnetic field generator to generate an AP magnetic field having at least a first frequency of 0.5-400 kHz and a first field strength of 0.2-5 mT, wherein the AP magnetic field selectively affects the cancer cells to prevent metastasis of the cancer cells, while leaving non-cancer cells substantially unharmed; and
a controller to control at least one of the first frequency and the first field strength of the AP magnetic field generated by the one or more AP electromagnetic coils.
