Abstract

1,193,916. Measuring magnetic fields. MAGNAVOX CO. March 29, 1968, No.15113/68. Heading G1N. In a magnetic field sensor, a magnetic core 21 is mounted within a non-magnetic casing 10 for free movement relative to a surrounding coil or coils, so that the core 21 may maintain a desired predetermined orientation despite movements of the casing 10. As shown, the core 21 is cemented to a brass ring 22 supported by brass screw threaded rods 23 on a non-magnetic disc 24 which is suspended from the top of the casing through a ball bearing joint (18). A toroidal primary winding 30 and four secondary windings 31 are wound round a plastics former 32 which has holes 36 in its lower annular surface to allow unobstructed movement of the rods 23. Screws 40 permit balance adjustment. The core may be arranged to maintain an orientation other than horizontal. The core may float on the surface of a liquid contained in the coil form.
