A ferromagnetic material having non-zero magnetoelasticity, and/or nonzero magnetostriction is driven with vibratory mechanical energy at a frequency producing at least one resonant vibratory mode, by coupling a source of vibratory energy to the ferromagnetic structure.

The ferromagnetic material threads at least one conductive wire or wire coil, and couples to at least one source of magnetic induction, and provides an electrical power output driven by the magnetic induction.

The origin of vibratory energy and the site or sites of magnetic induction are situated at distinct locations, separated by a specific distance not less than ? the fundamental acoustic wavelength.

Various combinations of acoustic wavelength, ferromagnetic material type, and source of vibration produce independent transfer coefficients between acoustic and electromagnetic energy which are either positive, zero, or negative. (Thanks to Norman Wootan for sharing this. Versions of this idea have been mentioned many times in Keelynet discussion lists, so its wonderful to see someone appears to have done it. - JWD) - Full Article Source
