1. An accelerometer comprising:
a rounded first magnetic assembly comprising a first concentrator extending from a first end having a first magnet to an opposing second end having a second magnet and forming a first gap between the first and second ends, the first magnetic assembly having a reduced width at each of the first and second ends and producing a non-linear first magnetic field between the first and second ends; and
a Hall sensor at least partially located within a first portion of the first magnetic field having first magnetic field lines extending in a first direction, wherein the Hall sensor or first magnetic assembly is configured to move to cause relative displacement of the Hall sensor perpendicular to the first direction.
