A model was developed for determining the space and time behavior of the magnetic field external to a system of conductors. A moving conductor is in relative close proximity to a stationary conductor that provides the source current. An additional conductor attenuates the environmental field. The space and time periodicity of the field are related to the parameters of the system. A numerical example predicts the magnitude of the magnetic field as a function of distance from the stationary conductor. Initial shielding considerations for mitigating the environmental effects produced by this class of emerging technologies were developed. The assessment indicates that conventional engineering design, based on the principles of electromagnetic compatibility EMC, can reduce the magnetic fields to levels consistent with the notional requirements of electric combat vehicles.
