<P>PROBLEM TO BE SOLVED: To provide a method for measuring a magnetic field applied to a plane. <P>SOLUTION: A first AC drive current is applied to a first strap, at least a part of the first strap lies down on a magnetoresistive sensor, the first strap has size extending in the first direction X, a second AC drive current is simultaneously applied to a second strap, at least a part of the second strap lies down on at least a part of the first strap, the second strap has size extending in the second direction Y, the second direction is not in parallel with the first direction, a phase of the second AC drive current is different from that of the first AC drive current, and the magnetoresistive sensor is influenced by a periodic rotation magnetic drive magnetic field which rotates on the plane of the magnetoresistive sensor. <P>COPYRIGHT: (C)2013,JPO&INPIT |
