ABSTRACT:
A plurality (e.g., an odd number) of CCD shift registers are provided in parallel, and a channel stop separates between the respective adjacent CCD shift registers and is partially cut out in order to make it possible for a carrier which passes through the CCD shift registers to move toward the side portion. Carrier (electrons) supplied from an input section to the center CCD shift register are measured at the outputs of the other CCD shift registers, and the intensity (the magnetic-flux density) of the magnetic field is determined on the basis of the absolute value thereof, and the direction of the lines of magnetic force is determined on the basis of whether the difference is positive or negative.
