Abstract

PURPOSE: To enhance the effect for elucidation of electromagnetic conversion mechanism by finding the unbalanced voltage without forming zero magnetic field, by measuring the Hall voltage plural times by changing the position of the Hall element in the uniform magnetic field.
CONSTITUTION: A Hall element 11 is placed in a uniform low magnetic field. By passing a constant control current Ic to a current electrode, a Hall voltage output VHl is obtained. This voltage contains an unbalanced voltage VH0 of the element 11. A Hall element 21 is rotated by 180 degrees in the same space on the Hall element magnetism-sensitive face, and an equal control current Ic is supplied to obtain a Hall output voltage of VH2. At this time, the unbalanced voltage of the element 21 is VH0. Hence, the average of two measurements of Hall output voltage may be the unbalanced voltage.
