Description

A number of metals, when subjected to a magnetic field, exhibit strain if they are free,or stress if rigidly clamped. This phenomenon, magnetostriction, has an inverse effect which leads to a change in magnetization when the metal is stressed. Inverse magnetostriction offers the possibility of application to the transduction of ultrasonic signals into initially magnetic and then electric signals. Considerable work has been carried out on magnetostrictive ultrasonic transducers [1], but little on the development of high bandwidth inverse magnetostrictive (IMS) transducers.
