In hysteresis materials it represents the energy dissipated in them during the cycle of magnetization & demagnetization (just refer any hysteresis loop diagram) .
This is used in many applications especially in aerospace to damp the oscillations in satellite.
The hysteresis loop for a stress - strain graph represents the energy per unit volume (energy density) that is transferred to internal energy during the loading and unloading cycle.
idk but can you ansswer my question i killed my dog and i dont know where to hide it Thanks please reply soon as possiblen
soft iron B-H curve area is very high and hysteresis loss is proportional to it frequency or no of loop cycles per sec and area of loop so hysteresis loss increases in soft iron as electro magnet
When a hysteresis loop is plotted on a graph ( X: Current, Y: Magnetic Field Strength ) for the core of any substance, the area covered by the loop (on both sides of the x-axis) will give the total energy involved or work done in one cycle of magnetisation and demagnetisation.
Hysteresis loops tell about the magnetic properties of a material. E.g. wider loops indicate that the material is magnetically hard (i.e. it retains magnetisation even if the applied field is removed, permanent magnetics have much wider hysteresis loops)whereas thinner loops represent it to be soft (if the magnetic field is removed, the material doens't show any magentism). This is one advantage of hysteresis loops. further, such loops can identify the grain size of a material and much more. hope it answers your question.

hysteresis losses
the leading or lagging between the stress and strain is called hysteresis loop
it is agm or vsm
hysteresis loss = N1/N2 R2/R1 C1/A1 (area of the loop)(vertical sensitivity) (horizontal sensitiivity

The material used in the manufacture of transformer cores must have a hysteresis loop with a very small area, as it is the area of the hysteresis loop that determines the hysteresis losses of the core material. The core material should also be resistive, in order to reduce eddy current losses (which is further improved by laminating the core). Many transformer manufacturers use their own variations on what is basically a silicon-steel.A hysteresis curve, or loop, is a graph of flux density plotted against magnetising force, and basically describes the ease (or difficulty) with which the core material can be magnetised and demagnetised as the magnetising current changes magnitude and direction.

this area represent the energy lost per cycle in ferromagnetic material during the magnetization process by hysteresis and in some cases also by eddy current magnetic losses and electric losses
A hysteresis loop is when the threshold to make a change in a system is different than the threshold to undo the change. Typically, in an op amp used as a switch, this is done with a small positive feedback, reducing the chance of oscillation when the input is near one of the two thresholds.
When I calibrate mine, I am stuck in an endless loop of calibration.
Hysteresis losses are a function of the magnetic characteristics of the magnetic circuit, so there is very little you can do to minimise hysteresis losses other than to reduce the primary voltage to a transformer if that is at all practicable. These losses are really in the hands of the manufacturers who design and manufacture magnetic circuits.
