It represents the energy lost when work is done by the rubber band, as it is lost as heat.
The loop, means loading minus unloading.
It is the amount the unloading curve SHOULD have covered, as in compress back to original, but it did not, hence the unloading curve 'lags' behind in coming back to original dimensions, and the curve represents that.
Since the unloading is not able to come back, that means that energy is not fully or efficiently converted back, hence it represents loss of energy which is in the form of heat.
Hope it helped :)
Natasha.
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.
Hope it helped.

A variable declared inside the for loop control cannot be referenced outside the loop?
Yes. A variable declared inside the loop is a local variable for the code block enclosed by the {} statements of the for loop. The variable will not be available to be used by any code outside the code block.
Why you use for loop inside switch statement?
Because you have to repeat something. (Or you can use while-loop, too.)
Which piece of pseudocode represents incrementing the loop control variable called count?
count = count + 1
Does a priming read appears inside the validation loop?
No, It appears out side.
How is a while loop different from a do until loop in gml?
In any programming language, a "while" loop and a "do until" loop are the same except for 1 difference. In order to enter a while loop, the condition must always be true. But in a do until loop, if the condition was false, the block of code inside the loop will always be ran at least once. Example: while (false) { // code here } in this example, the code inside the while loop will never run, but in the following example: do { //code here } until(false) although the condition is false, the code will be run 1 single time and the exists the loop.
What is hysteresis loop in stress and strain?
the leading or lagging between the stress and strain is called hysteresis loop
What is hysteresis calibration loop?
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.
How can you measure the hysteresis loop of the ferroelectric materials and what is the name of the instruments used for the measurements of the hysteresis loop?
it is agm or vsm
Why Soft Iron is suitable for preparing electromagnets?
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
Formula of Hysteresis loss and Eddy current loss?
hysteresis loss = N1/N2 R2/R1 C1/A1 (area of the loop)(vertical sensitivity) (horizontal sensitiivity
What is the significance of looping?
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 area of hysteresis loop in a ferromagnetic material of?
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
How do you determine the work done in a ferromagnet in going round a hysteresis loop?
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.
A contour line that forms a closed loop and has small dashes pointing to the inside of the loop represents?
A depression in the ground.
How do you select core in Transformer Design?
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.
A contour line that forms a closed loop and has small dashes pointing to the inside of the loop represents what?
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.
How do you reduce the hysteresis loss?
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.
