The magnetic fields we propose here are substantial in magnitude, but very local in space. The magnetic fields are assumed to be a low estimate, as we compute them at a very low bias, which can often be higher in single-molecule junctions depending on the experimental setup. Furthermore, we use s-band approximated electrodes to compute the transmission, which is underestimated relative to DFT computations that include full Au electrodes; albeit those computations are known to overesti-mate the transmission relative to experimental single-molecule conductance values. Finally, we note that we have only computed the magnetic field that arises directly from the ballistic current, and the response properties of the molecule are therefore not accounted for.
