Patent ID: 7338431

Claim:
A system for stimulating immune systems of biological entities, said system comprising: at least one electric current generator providing a source of pulsed electrical current; at least one continuous coil of electrically conductive material having a first end and a second end, both of said ends being connected to said at least one generator to form a closed circuit such that said at least one coil emits a spatially non-uniform pulsed magnetic field in response to said pulsed electrical current, and wherein a configuration of said at least one coil comprises a plurality of turns of said conductive material in substantially a single spatial plane, and wherein said coil has an overall width-to-length ratio of between 0.4 and 0.8; and an environment containing said at least one continuous coil, wherein said environment includes at least one of a livestock yard, a garden, an orchard, an athletic ground, and a play ground.
