Nowadays, many companies produce a survey of precise and proven instrumentation based on well-established characterization techniques to efficiently characterize a variety of sample magnetic materials: vibrating sample magnetometers, susceptometers/magnetometers, SQUID magnetometers, BH meters, AC/DC hysteresigraphs, coercimeters, pulsed field magnetometers, electromagnets, superconducting magnets, cryogen-free magnets, Helmholtz coils, capacitor discharge magnetizers, fluxmeters, Hall effect Gaussmeters, and magnetic calibration standards.
