While a typical material exhibits field induced currents only at theboundary, a uniform out-of-plane magnetic field applied to two mutually rotatedlayers of graphene is shown to result in an ordered array of permanent currentloops throughout the material. Each current loop consists of an interlayercurrent flowing through the open AA stacked regions of the moir\'e created byrotation, which then flows back through the neighboring AB regions to form acircuit, with significant current strength even at small fields. Similarmoir\'e ordered arrays of current loops are also shown to exist innon-equilibrium transport states, where they manifest as current back flowingagainst the applied bias in the device. Such current loops thus represent anintrinsic feature of the twist bilayer in conditions of broken time reversalsymmetry, and exist both as a low field imprint of the moir\'e lattice onLandau physics, and as measurable moir\'e scale current configurations intransport states.
