what does the area under B-H curve show ??
A B-H curve plots changes in a magnetic circuit's flux density as the magnetic field strength is gradually increased.
The resulting shape indicates how the flux density increases due to the gradual alignment of the magnetic domains within the magnetic circuit material.
When all the domains have aligned, the B-H curve reaches a plateau and the magnetic circuit is said to be saturated.
At this point, any further increase in magnetic field strength has no further effect on the flux density.
After reaching saturation, a reduction in the magnetic field strength results in a reduction in the flux density.
However, the resulting curve does not quite match the original curve, but 'lags behind' it. This effect is called hysteresis, which is from the Greek, meaning to 'lag behind'.
The area under the B-H curve denotes Hysteresis loss
