Principle

It works under the principle of Magnetostriction effect.

When a ferromagnetic rod is kept in an alternating magnetic field the rod is set into longitudinal vibrations, this happens due to change in the length of the rod.

This longitudinal vibrations, result in the formation of ultrasonic waves at resonance. …
