Abstract: The disclosure relates to a gyroscope in which an electric signal corresponding to an angle (-.alpha., +.alpha.) between the rotor of the gyroscope and the frame of the rotor is generated. The rotor is provided with one or more permanent magnets. An element of magnetic material is disposed in the frame of the rotor so that the latter may move in relation to the element during its rotation. The element may be passed by the magnetic fields of the permanent magnets during rotation of the rotor so that magnetic flux changes occur in the element. The element is arranged such that the flux changes are dependent upon the above-mentioned angle and the flux changes are sensed by an electric induction winding which generates the electric signal.
