1. An apparatus comprising:
a magnetic device extending at least along an x-axis, a y-axis, and a z-axis, wherein the magnetic device is configured to determine a perpendicular magnetization that extends along the z-axis and further configured to determine a parallel magnetization that extends along the x-axis, wherein the x-axis is perpendicular to the z-axis, the x-axis is perpendicular to the y-axis, and the z-axis is perpendicular to the y-axis;
first magnetic shielding comprising a first magnetic material, the first magnetic shielding extending at least a first distance along the z-axis and extending at least a second distance along the y-axis, wherein:
the first distance is a distance between a first outer surface of the magnetic device and a second outer surface of the magnetic device in the z-axis,
the second distance is a distance between a front of the magnetic device and a back of the magnetic device in the y-axis,
the first outer surface is on an opposite side of the magnetic device from the second outer surface of the magnetic device and wherein the front of the magnetic device is on an opposite side of the magnetic device from the back of the magnetic device; and
second magnetic shielding comprising a second magnetic material, the second magnetic shielding extending at least a third distance along the x-axis, wherein;
the third distance is a distance between a third outer surface of the magnetic device and a fourth outer surface of the magnetic device in the x-axis,
the fourth outer surface is on an opposite side of the magnetic device from the third outer surface of the magnetic device.
