Multiple BH loops are needed in play model calculations. Measurements can take up a large amount of time, often with the measurements between finer intervals also proving difficult. JMAG-Designer can generate groups of symmetric hysteresis loops based on the LLG equation (the Landau–Lifshitz–Gilbert equation) from minor measurement data, and calculate hysteresis loss using play models.
This document describes the method for creating groups of symmetric hysteresis loops by using tools from the measurement data of a single BH loop.
