We report on a radio frequency magnetometer employing a Bose–Einstein condensate of 87 Rb atoms held in a dipole trap. An AC sensitivity of [Formula: see text] is achieved at a probing volume of [Formula: see text], leading to a volume-normalized sensitivity of [Formula: see text]. At larger probing volumes with the atoms released from the magnetic trap used in the initial phase of the evaporation sequence, the AC sensitivity is improved to [Formula: see text], allowing a two-mode approach for applications requiring improved sensitivity. Immediate application in high-resolution electromagnetic induction imaging is expected when compared to performance of other induction-based imaging platforms.
