Question

Which of the following accurately describes the BH curve? ( Select all that may apply )

Answer

The operating region is the segment of the curve just before saturation occurs ( the knee point ).

Answer

Complete saturation is the point when there is an exact proportional increase in material's flux density as the field intensity is increased.

Answer

The operating region is when any applied H causes little increase in B.

Answer

The BH curve is usually approximated as two linear regions.

Answer

The slope of the saturation region is equal to the permeability of free space.
