When an electric charge moves around a closed circuit, it forms an electric current, and when a magnetic field is imposed upon the current, an electromagnetic force results [1]. It has long been known that the sliding of leather on wood results in the buildup of high electric charge in the leather [2]. For leather-soled dancers on wood floors, electric currents are generated during couple- or group-formations. The induced electromagnetic force is typically negligible compared to the forces of friction, centrifugal motion, and gravity. Only during Christmases with a high Murphy Index [3,4] has the force been large enough to be observed [5].

In recent years, a variation of the Christmas routine involving the Scullen Counter-Rotating Reference Frame (SCRRF) [6] has had the effect of amplifying the electromagnetic force. In a few instances when the SCRRF has been combined with a high Murphy Index-Christmas, levitation has been observed [7], an effect dubbed the Scullen-Murphy Phenomenon (SMP).

In this paper, the author will present a mathematical analysis of SMP and comment on any possible implications for homeland security.
