Abstract
PURPOSE: To make a big Hall output voltage obtainable, by enabling a considerably intense magnetic field provided even at a light load, with a ferrite core located in a magnetic field produced by an insulated conductor wound in a spiral-shape.
CONSTITUTION: A load current IL is applied through an insulated wire 13, wound in a spiral-shape, of electromagnet, and the magnetic field, proportional to a level of the load current, is constructed in the electromagnet 12, which is applied to a Hall element 11 as the field. Accordingly, even at a light load, a considerably intense magnetic field comes to be provided thus with a big Hall output voltage obtainable.
