This patent application discloses an optical fiber for magnetostrictive responsive detection of magnetic fields. The strength of the protective magnetic field is determined by standard interferometry techniques by comparing the phase or mode properties of the light from a light source exiting the fiber having a magnetostrictive jacket against the phase or mode properties of light from a light source exiting a reference fiber having pre-determined or identical light transmission properties. The sensitivity of magnetic effect upon the magnetostrictively affected fiber is enhanced by subjecting the magnetostrictive material to a quantitative low-level magnetic field.
