Material table data for the GenericHystTellinenTable flux tube element. The records contain two data tables tabris and tabfal describing the rising and the falling branch of the hysteresis envelope curve of the corresponding material. The first column is the magnetic field strength H and has to be strictly monotonically increasing. The second column contains the corresponding values of the magnetic fluxdensity B. Both curves may not intersect each other.

Fig. 1 and Fig. 2 show library entries based on own measurements of several steel sheet qualities in two different ranges of the magnetic field strength. For the measurements a 25 cm Epstein frame was used according to DIN EN 60404-2.
