1. A system for magnetic field measurement, the system comprising:
a container;
at least one particle within the container, wherein the at least one particle moves within the container in response to a magnetic field; and
a measurement circuit configured to output an indication of the magnetic field based on position of the at least one particle, wherein the measurement circuit comprises circuitry of an integrated circuit, and wherein the integrated circuit is co-packaged with the container.
