B-H CURVE or HYSTERESIS LOOP
On application of a magnetic field on a ferromagnetic material It shows a non linear rise (1)Flux Density lags behind the applied external field called as |
Why is BH curve nonlinear?
So the ratio of flux density to field strength ( B/H ) is not constant but varies with flux density which gives non-linearity to the B-H curve.
$B$ denotes the magnetic flux density and H represents the magnetic field strength.
The curve shows how commercial iron responds to magnetisation.
Commercial iron is the form of iron containing carbon and other impurities in small amounts.
What is the BH curve for hysteresis loss?
It is important that the B-H hysteresis loop is as small as possible so loss will be less because shape of B-H curve decides the loss.
Bigger the area then more is the loss and vice-versa.
The shape of hysteresis loop depends upon the nature of the material used i.e. iron or steel.
What is the BH curve?
The B-H curve, also known as the magnetization curve or hysteresis curve, is a graphical representation that describes the magnetic properties of a material.
It shows the relationship between the magnetic field strength (H) and the magnetic flux density (B) of a material.17 oct. 2023
