Abstract

In this paper the magnetostrictive behaviour of ribbons and wires is revisited and studied, proposing an analytical modelling followed by experimental validation using the magnetostrictive delay line (MDL) method, due to the needs for engineering applications of magnetostriction, like sensors and transducers. The obtained results may be used for the determination of the M(H) and λ(H) functions as well as their uniformity distribution along the length of magnetostrictive ribbons and wires, which is a key-factor for the characteristics of sensors based on the magnetostriction effect..
