Abstract

PURPOSE:To enable the reduction of noise and error produced due to electromagnetic induction with an outer magnetic field, by a method wherein an outgoing conductor part, ranging from a magnetic resistance effect element to a measuring device, is connected in a manner to form 2 loops being in the reverse direction to each other. CONSTITUTION:If only a first conductor 7 and a second conductor 3 are connected to a first terminal 4 and a second terminal 5, respectively, noise is produced due to electromagnetic induction when a loop, formed with the conductors, is interlinked with an outside alternating magnetic field. Therefore, a third terminal 6, being placed, is connected directly to the second terminal 5, a third conductor 9 is connected to the third terminal 6, and the conductors are located such that a loop, formed by the first and second conductors, and a loop, formed by the first and third conductors, equalize in the area. Through the passge of the outside alternating magnetic field through the two loops formed by the 3 conductors, noise is produced in the two loops, but the noise is eliminated because of the mutual absorption.
