Abstract

Since magnetic phenomena have been applied to many kinds of fields, the requirement for precise and simple measurement of the magnetic field is increasing. In this paper, we propose a novel method for imaging the magnetic field as a vector quantity on any layer, applying a computed tomography (CT) algorithm used widely in the field of clinical medicine to the electromagnetic induction phenomenon. Since this method can measure the magnetic field distribution only by applying the CT algorithm to voltage induced in a line conductor and a rectangular coil moving in the field at a fixed speed, it is much easier to measure the distribution with this method than the conventional method by Hall sensor or other methods. We also performed an imaging experiment of the magnetic field produced by some permanent magnets to verify the efficacy of this method.
