Abstract: A system including a primary coil assembly is provided. The primary coil assembly is configured to operate at a first resonant frequency having a first bandwidth; wherein a difference between the first resonant frequency and a system frequency is at least two times the first bandwidth, where the first resonant frequency is selected such that upon energizing the primary coil assembly at the system frequency, a primary current is induced in the primary coil assembly, which is at least ten times lesser than a system current.
