Hydrodynamically stable rotating flows can be destabilized by an azimuthal magnetic field. The arising non-axisymmetric, or azimuthal magnetorotational instability (AMRI) is important for explaining the angular momentum transport in accretion disks, and plays a central role in the concept of the MRI dynamo. We report the observation of AMRI in a magnetized liquid metal Taylor-Couette experiment, and discuss the surprisingly strong effects of a slight symmetry breaking of the applied magnetic field.
