Can you measure hysteresis loss for diamagnetic materials?
what is hysteresis losses
Is hysteresis loss considered heat loss?
In general even though energy is lost during hysteresis it is not called as heat losses . Generally I2R losses are called as heat losses because in these tye of only in these energy is lost in the form of real heat
The area inside the hysteresis loop represents?
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. Ninad
How can hysteresis loss in magnetic material may be reduced?
Hysteresis losses depend on the type of metal used to manufacture the magnetic circuit of a machine. Most magnetic circuits are made from silicon steel. Generally speaking, there's not much you can do to reduce hysteresis losses as that has already been factored in by the machine's designer.
What is difference between eddy current loss and hysterisis loss?
Whenever rotor cuts the magnetic field, emf is induced it. Due to this emf, some current may flow in the rotor. This current is called Eddy current which is unnecessary and considered a loss called Eddy current loss. When a magnetic material is energised it follows B-H curve and when de-energised, it does not follow B-H curve. This difference is considered a loss called Hysterisis loss.
Formula of Hysteresis loss and Eddy current loss?
hysteresis loss = N1/N2 R2/R1 C1/A1 (area of the loop)(vertical sensitivity) (horizontal sensitiivity
How do you calculate the Hysteresis loss given a B-H curve?
hysteresis loss= K B^1.6 egs/sec where k is STEINMEITZ coefficient and B is the maximum magnetic flux density

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
How do you find the loss factor in hysteretic damping?
Loss factor is best obtained by dynamically loading (extensional, torsional etc.) a specimen of the material and plotting the hysteresis curve in stress-vs strain plane. If the total area under the hysteresis loop is D, the loss factor is computed from the following formula Loss factor=D/(2*pi*max stress* max strain) For lightly damped materials, loss factor is just twice the daming factor 'zeta' which obtained either by log-decrement method or half-power bandwidth method.

Does a diamagnetic substance exhibit hysteresis loss?
No
Causes of hysteresis loss in transformer?
No, you're hysteresis losses are set by Bmax, frequency, and material. The function is highly nonlinear and the loss goes up disproportionately with Bmax. When designing power transformers, you typically want the hysteresis + eddy losses to equal the copper losses.
Steinmetz equation for iron loss?
Steinmetz equation The loss of energy per cycle per volume is given by Steinmetz's equationwhere B is the maximum induction and is the hysteresis coefficient.

What is the Technical meaning of CRGO Lamination?
To minimize hysteresis loss
