The following points need to be satisfied while defining the BH curve.
┬ÀFor a Normal BH curve, the slope of the curve cannot be less than that of free space anywhere along the curve.
┬ÀThe value of B must increase along the curve. (Please add points in order accordingly)
┬ÀThe first data points for B and H must be 0 (zero).
┬ÀThe data points representing the BH curve should have enough points for an accurate representation of the curve.20 or more points should be specified with increased representation on the "knee" of the curve.

┬ÀSince BH operating points in the FEA solution may extend beyond the input BH data set, the BH data set is extrapolated in Maxwell.The slope of the last two user-defined data points is used to extrapolate the BH curve, and thus should be as close to mu0 as possible.
