Abstract
An induction coil having two split-ring cores which are self-aligning. Each core is semi-circular, one core being fixed within a first jaw, and the other free to move within a second jaw. The jaws are pivotally attached and biased to form a closed loop in the relaxed state. A spring next to the free core urges the free core against the fixed core as the jaws are brought together. This action insures a proper contact between core ends which is necessary for optimum inductive coupling.
