A magnetic field therapy apparatus includes a first wire coil, a second wire coil and an electrically conductive member connecting the coils in series. The coils are wound in the same direction. In a preferred embodiment the coils are wrapped around a single bobbin, with the first coil forming a bottom layer and the second coil wrapped around the first coil and forming a top layer. AC power coupled to the coils energizes the coils and generates a magnetic field within the bobbin interior region. When current enters one coil it induces current in the other coil, thereby creating a scalar effect, producing energy in the form of a helix. The waves are identical, but out of phase temporally, that is, physically identical, but 180 degrees out of phase in terms of time. In an alternate embodiment, the coils may be on separate bobbins. A trigger may be applied to the part of a body undergoing therapy.
