Search coils for detecting magnetic fields can be improved by the used of metallic glass. The standard many-turn coil is mounted on a hollow dielectric rod wound with flexible metallic glass. The resulting coil will detect magnetic fields better than the standard coil installed with a ferrite material, especially for frequencies of 30 Hz and higher. This new device is lighter in weight and can be made rugged. Three such coils can be used to measure three orthogonal components of the magnetic field. With the increasing interest in magnetic devices, especially the new super magnets, this coil construction many have considerable application.
