Abstract: A magnetic sensor apparatus includes a substrate, a plurality of magnetoresistance sensor units, a reset coil and a compensation coil. The magnetoresistance sensor units are disposed on the substrate. The reset coil is disposed over the magnetoresistance sensor units for introducing a resetting current, and a magnetic field generated from this resetting current can be used to reset magnetization directions of the magnetoresistance sensor units. The reset coil includes a plurality of first main segments. The compensation coil is disposed over the magnetoresistance sensor units for introducing a compensating current, and another magnetic field generated from the compensating current is used as a compensation magnetic field onto the magnetoresistance sensor units. The compensation coil includes a plurality of second main segments. The first main segments of the reset coil are perpendicular to the second main segments of the compensation coil.
