    "normal" determination to estimate permeability

    I'm working on a magnetic circuit using a cast steel rectangular core with a .0008m air gap.

    There is a hint the question that says, 'Use a "normal" determination to estimate μ from the graph.'

    What exactly is a "normal" determination referring to??

    This might help, from,


    See figure 4. Some of the text nearby,

    "... For many engineering applications it is sufficient to describe the material using the dc or normal magnetization curve, which is a curve drawn through the maximum values of B and H at the tips of the hysteresis loops (Fitzgerald et al. 1990). ..."
