1. A magnetic field device, comprising:
- a first magnet;
a first ferromagnetic element positioned adjacent to the first magnet;
a second magnet;
a second ferromagnetic element positioned adjacent to the second magnet and relative to the first ferromagnetic element to create a gap between the first ferromagnetic element and the second ferromagnetic element; and
a third magnet positioned between the first ferromagnetic element and the second ferromagnetic element and within the gap.

20. A method of directing magnetic fields into a measurement volume, the method comprising:
-
generating a first magnetic field in a first direction with a first magnetic field strength; distributing the first magnetic field into the measurement volume to create a substantially uniform magnetic flux; and increasing a total magnetic flux into the measurement volume by directing a second magnetic field in a second direction with a second magnetic field strength, wherein the second direction is parallel to the first direction. - View Dependent Claims (21, 22, 23, 24, 25)
