Abstract
A movement for instrument is of thin construction. A rotatably supported shaft extends through a thin magnet and supports the magnet on it. The magnet radiates a magnetic field that varies in magnetic field strength in accordance with a sine function along a circular path about the shaft. A signal generator provides a first current and a second current. First straight conductors are disposed in a first direction parallel to the surface of the thin magnet, are laid in the magnetic field of the magnet, and are supplied with the first current through them. Second straight conductors are disposed in a second direction parallel to the surface of the magnet and transverse to the first direction. The second conductors are laid in the magnetic field of the magnet and are supplied with the second current through them. Thus, the magnet is angularly positioned in accordance with the magnitudes and directions of said first and second currents, thereby causing the pointer to indicate the angular position of the magnet.
