This paper introduces the MagNetX1- an extension of the MagNet database to investigate transient hysteresis of magnetic materials. By employing automated data acquisition and measurement systems, detailed transient phenomena are observed and evaluated across a wide range of waveforms and operational conditions. Results reveal significant core loss variations during frequency transitions, and the B-H loop analysis further demonstrates loop area changes during transient phases. The platform enables advanced data-driven modeling of core losses and hysteresis loops over a wide range of amplitudes, frequencies, temperatures, and duty cycles under transient conditions, which are critical for practical circuit design when steady-state models are inadequate, such as modeling the magnetic core behaviors in ac-dc converters, motor drives, or power amplifiers.
