We investigate AdS3 and AdS2 magnetic brane solutions within the consistent truncation of AdS5 × S5 supergravity. The AdS3 solution extends earlier work by allowing a general embedding of the magnetic U(1) in SO(6). We determine the ratio of strong- and weak-coupling entropies as a function of this embedding. Further, by considering crossed magnetic fields in different U(1)'s we are able to construct a solution that runs from AdS5 in the UV to AdS2 × R3 in the IR. We find the notable result that there is a zero temperature entropy at strong coupling but not at weak coupling. We also show that the AdS2 solution and at least some of the AdS3 solutions are stable within the truncation.
