1. A device for sensing a magnetic field associated with an individual, comprising:
a. an array of magnetometers configured to sense the magnetic field associated with the individual;
b. a shield configured to shield at least the array of magnetometers from an ambient magnetic field,
wherein the shield is sized to at least partially enclose at least a portion of a body of the individual,
wherein the shield comprises an open end and a closed end,
wherein the open end is configured to receive the portion of the body of the individual,
wherein the closed end comprises a tapered shape or a conical shape, and
wherein the shield comprises a plurality of layers, a permalloy, or a mumetal, and reduces noise from the ambient magnetic field including noise from an ambient magnetic field of the Earth, and wherein the tapered shape or the conical shape of the closed end is configured to further improve noise reduction of the shield; and
c. a non-transitory computer-readable medium encoded with a computer program comprising instructions executable by a processor, the instructions configured to cause the processor to receive the magnetic field associated with the individual sensed by the array of magnetometers.
