A susceptometer includes: a substrate; a plurality of electrodes including: a first pair of electrodes disposed on the substrate; a second pair of electrodes disposed on the substrate, the second pair of electrodes arranged collinear with the first pair of electrodes to form a set of aligned electrodes; and a third pair of electrodes disposed on the substrate, the third pair of electrodes arranged noncollinearly with set of aligned electrodes; and a solenoid circumscribingly disposed around the electrodes to: receive the sample such that the solenoid is circumscribingly disposed around the sample; receive an alternating current and produce an primary magnetic field based on the alternating current; and subject the sample to the primary magnetic field.
