  We discuss analytic solutions describing magnetically charged black branes in
$d$ dimensional AdS space. Focusing on $d=5$, we study the response of the
brane to an external short lived electric field. We argue that when the theory
possesses an 't Hooft anomaly then at sufficiently low temperature a long lived
oscillatory current will be observed long after the electric field has been
turned off. We demonstrate this ``anomalous resonance'' effect via a numerical
study.
