Abstract
A magnetic transmitter including at least one magnetoelastic element, a magnetic field source, and an actuator operably coupled to the magnetoelastic element. The magnetoelastic element is oriented parallel to the magnetic field source. The magnetic field source is configured to induce a magnetic flux in the magnetoelastic element, and the actuator is configured to induce harmonic vibration in the magnetoelastic element. The magnetoelastic element is oriented parallel to the magnetic field source. The harmonic vibration of the magnetoelastic element is configured to change a net magnetic dipole of the magnetic transmitter due to magnetostriction.
