An apparatus for excitation of peripheral nerves which is made of a pair of vertically overlapped arc-shaped cores. The cores are brought together with one leg of one arc-shaped core vertically overlapping one leg of another arc-shaped core in a central region. The resulting common central leg of the two arc-shaped cores is wound by a coil and the return path for the flux is split between the non-common legs of the two arcs. In one preferred embodiment, each of the arc-shaped cores spans an angle of approximately 210 DEG . The vertically overlapping core is preferably made of a highly saturable material. |
