ABSTRACT:
The present invention is directed to a gyroscopic instrument comprising concentric containers, the inner container enclosing a rotating electric gyro rotor, magnetic fluid enclosed between the inner and outer concentric containers, and magnetic flux producing means mounted on at least one of the two concentric containers, so that magnetic fluxes reach the magnetic fluid to support the inner container without contacting the outer container. The magnetic flux producing means are preferably mounted and oriented on a line drawn on at least one of the concentric containers at predetermined distances so that magnetic fluxes transmitted from the pole of one flux means reach the opposite pole of an adjacent means by passing through the magnetic fluid.
