Magnetic Circuits

The horizontal axis H on this image of an Hysteresis Loop represents:

• magnetising force

• flux density

• residual magnetism

• coercive force

The Vertical axis B on this image of an Hysteresis Loop represents:

• magnetising force

• flux density

• residual magnetism

• coercive force

-H_c and H_c on this image of an Hysteresis Loop represent:

• magnetising force

• flux density

• residual magnetism

• coercive force

-B_r and B_r on this image of an Hysteresis Loop represent:

• magnetising force

• flux density

• residual magnetism

• coercive force

The flat area at the top of each of the three lines on the graph shown is called:

• high gain region

• saturation region

• residual magnetism region

• useful region

The best metal for use in AC equipment magnetic circuits is:

• air ( not shown on graph)

• cast iron

• cast steel

• silicon steel
