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.
Abstract translation: 磁体包括具有长度和宽度的磁体。 主体在一侧具有第一凹口并且沿着主体的长度的至少一部分延伸，并且在主体的相对侧的第二凹口沿主体的至少一部分长度延伸。 由身体产生的磁场沿着身体长度的至少一部分具有基本均匀的磁通量。 用于检测目标的系统包括位于具有基本上均匀通量的磁场部分内的一个或多个磁场感测元件。
