Abstract
A magnetic field sensing apparatus including a substrate, a plurality of magnetoresistance sensors and a plurality of magnetization direction setting devices is provided. A surface of the substrate includes a plurality of inclined surfaces and a plane surface. The magnetoresistance sensors include a plurality of first magnetoresistance sensors disposed at the inclined surfaces and a plurality of second magnetoresistance sensors disposed at the plane surface. The first magnetoresistance sensors include a first and a third portions and form a first full Wheatstone Bridge. The second magnetoresistance sensors include a second and a fourth portions and form a second full Wheatstone Bridge. The magnetization direction setting devices include a first and a second magnetization direction setting devices. The first magnetization direction setting device is disposed beside and overlaps with the first and the second portions. The second magnetization direction setting device is disposed beside and overlaps with the third and the fourth portions.
