ABSTRACT:
One embodiment relates to a method of manufacturing a magnetic sensor. In the method, an engagement surface is provided. A magnet body is formed over the engagement surface by gradually building thickness of a magnetic material. The magnet body has a magnetic flux guiding surface that substantially corresponds to the engagement surface. Other apparatuses and methods are also set forth.
