Abstract:
A magnet includes a magnetic body having a length and width. The body has a first notch in one side and extending along at least a portion of the length of the body, and a second notch in an opposite side of the body extending along at least a portion of the length of the body. A magnetic field produced by the body has a substantially uniform magnetic flux along at least a portion of the length of the body. A system for detecting a target includes one or more magnetic field sensing elements positioned within the portion of the magnetic field having substantially uniform flux.
