1. A system for generating a magnetic field having a desired magnetic field strength and a desired magnetic field direction, the system comprising:
a first magnet having a first magnetization direction, the first magnet comprising a plurality of first magnetic segments, wherein:
each of the plurality of first magnetic segments is positioned adjacent to another first magnetic segment of the plurality of first magnetic segments,
each of the plurality of first magnetic segments has a magnetization direction, and
the magnetization direction of at least one magnetic segment of the plurality of first magnetic segments is different than the magnetization direction of at least one other magnetic segment of the plurality of first magnetic segments;
a second magnet having a second magnetization direction, the second magnet being adjacent to the first magnet, and the second magnet comprising a plurality of second magnetic segments, wherein:
each of the plurality of second magnetic segments is positioned adjacent to another second magnetic segment of the plurality of second magnetic segments,
each of the plurality of second magnetic segments has a magnetization direction, and
the magnetization direction of at least one magnetic segment of the plurality of second magnetic segments is different than the magnetization direction of at least one other magnetic segment of the plurality of second magnetic segments; and
a ferromagnetic element adjacent to the first magnet, wherein:
the ferromagnetic element comprises a plurality of ferromagnetic segments, and
each of the ferromagnetic segments is positioned adjacent to at least one other of the plurality of ferromagnetic segments.
