Abstract
A magnetostrictive wire element made of amorphous ferromagnetic material is tailored for installation within a sensor by treatment which includes annealment by heating while a stress condition is imposed thereon, and applying a DC electric current thereto during said annealment to produce a cylindrical magnetic field relative to the wire element establishing spiral magnetic anistropy during cooldown after said heating.
