1. A method for forming a magnetic sensor, comprisingproviding an engagement surface;

  • depositing an epoxy layer on the engagement surface, a surface of the epoxy layer formed having three planar surfaces; and

    forming a magnet body over the engagement surface and on the epoxy layer by gradually building thickness of a magnetic material, the magnet body having a magnetic flux guidance surface having three planar surfaces and being substantially v-shaped to facilitate perpendicular guidance of magnetic field lines.
