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
Why is it important to use a soft magnetic material as the core of a solenoid?
Soft iron is having very low hysteresis loss. So it would be good to use it as core.
What name is given to loss water from the leaves?
Transpiration
Why is steel not used to make electro magnets?
steel is note for an elecromagnet because once it turned magnetic it stays magnetic
Why cooling curve of crystalline solids have breaks?
Cooling curve of Crystalline solids have breaks, which corresponds to the begining and ends of the crystallisation process. The temperature remains constant during crystallization as the process is accompained by some liberation of energy, which compensates for the loss of heat and causes the temperature to remain constant. -Damodar
What is the formula of energy loss in hysteresis curve?
P/Vol=A/T P: Power Vol: Volume A: Area T: Period
Can you measure hysteresis loss for diamagnetic materials?
what is hysteresis losses

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.
Formula of Hysteresis loss and Eddy current loss?
hysteresis loss = N1/N2 R2/R1 C1/A1 (area of the loop)(vertical sensitivity) (horizontal sensitiivity
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
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.

Why core is made up of silicon steel?
produces magnetic properties,such as small hysteresis area and permeability Hysteresis loss depends upon the material of the core
Why armature core is laminated in dc machine?
to reduce the eddy current loss in the machine
