An improved shielded magnetometer including a resonant probe containing a magnetically resonating material held in a resonator. The magnetometer has a spherical electromagnetic shield which exhibits improvements in the sensitivity characteristics by removing the effects of interference fields when the magnetometer is rotated about its axis.
