The presence of dark matter provides some of the most tangible evidence for the existence of physics beyond the Standard Model. One compelling dark matter candidate is the axion, a light boson that was originally postulated as a solution to another outstanding issue, the strong CP problem in QCD. ABRACADABRA is an experimental program to search for sub-$\mu$eV axion and axion-like dark matter. It searches for axion-induced modifications to Maxwell’s equations with a toroidal magnet and SQUID magnetometer. This talk will present COMSOL simulations made to test aspects of the prototype detector, ABRACADABRA-10cm, and to prepare for a future, full-size detector, ABRACADABRA-1m. These simulations include R&D for different detector geometries as well as measurements of the detectors’ geometric factors and readout inductances.
