Abstract:
A frequency generator for treating cells of a similar type, comprising:a plurality of permanent magnets arranged in a side-by-side relationship with the magnetic north pole and the magnetic south pole of each permanent magnet being adjacent the magnetic north pole and magnetic south pole of an adjacent permanent magnet, respectively, the plurality of permanent magnets forming a ring of permanent magnets;a wire of electrically conductive material wound substantially around the ring of permanent magnets so as to form a coil;tubing wrapped around the ring of permanent magnets between windings of the wire;a cooling device for introducing a flow of coolant through the tubing; anda control circuit, connected to the wire, for selectively generating a coil current for passing through the wire, the current having an AC component and a DC component, the AC component having a frequency that is programmable to substantially match a resonant frequency of the cells to be treated, the coil current creating an electromagnetic field which interacts with a magnetic field generated by the ring of permanent magnets so as to generate a complex field that is applied to the cells to be treated.
