Abstract: The principal points relating to the quality of the photoelectric visual magnetograph are discussed. It is shown that the value of the coil constant is determined by the range of the magnetic field to be registered and the range of the point writer chosen. The scale value of the magnetograph should be as small as possible. It is advantageous that if the rectangular image on the photo-cell is made narrower.
