Abstract

PURPOSE: To prevent occurrence of measuring mistakes and simplify the operation of measuring the magnetic polarity by sensing the magnetic polarity of the magnetic pole being measured according to the direction of the Hall voltage of a Hall element.
CONSTITUTION: Hall ICs 5 and 6 are placed near a magnetic pole to be measured, and a push-button switch 2 is closed. When the magnetic pole is north, the potential level at an output terminal 5g of the Hall IC5 is made low and a light-emitting diode 7 is turned on. On the other hand, when the magnetic pole is south, the potential level at an output terminal 6g of the Hall IC6 is made low and a light-emitting diode 8 is turned on.
