Abstract

This application relates to devices that utilize magnets and associated magnetic sensors. A magnetic sensor can be positioned and oriented with respect to a magnetic element such that the magnetic sensor is capable of detecting a horizontal magnetic field component in contrast to the conventional paradigm of detecting a vertical magnetic field component. This can be accomplished by orienting a magnetically sensitive surface of the magnetic sensor about ninety degrees with respect to a magnetic vector of the magnetic element.
