Abstract
A magnetic field measurement system can include at least one magnetometer; and a ferrofluid shield disposed at least partially around the at least one magnetometer. For example, the ferrofluid shield can include a microfluid fabric and a ferrofluid disposed in or flowable into the microfluid fabric. As another example, the ferrofluid shield can include a ferrofluid and a controller configured to alter an arrangement of the ferrofluid within the ferrofluid shield.
