Abstract
A mechanically resonant system exhibits a resonant mode frequency response. A conductor is included on a resonant member within the mechanically resonant system. A current in the conductor causes a modification of the resonant mode frequency response when in the presence of a magnetic field. The modification of the resonant mode frequency response may include an offset in the natural frequency of the mechanically resonant system.
