BEC Magnetometer

Current running through a wire, laser light, and an applied magnetic field can be used to position an extended Bose Einstein condensate (BEC) of chilled atoms (the blue lozenge) to sense magnetic properties, with high precision, in an underlying sample. The inset picture shows how the BEC (profile indicated by the blue circle) is positioned by changing the applied magnetic field.
