hysteresis loss= K B^1.6 egs/sec where k is STEINMEITZ coefficient and B is the maximum magnetic flux density
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
Soft iron is having very low hysteresis loss. So it would be good to use it as core.

steel is note for an elecromagnet because once it turned magnetic it stays magnetic
An adiabatic process is a thermodynamic process, there is no gain or loss of heat.

what is hysteresis losses
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.
hysteresis loss = N1/N2 R2/R1 C1/A1 (area of the loop)(vertical sensitivity) (horizontal sensitiivity
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.
To identify and calculate deadweight loss on a monopoly graph, you can look for the area of the triangle between the demand curve, the supply curve, and the monopoly's marginal cost curve. This area represents the loss of economic efficiency due to the monopoly's market power. You can calculate the deadweight loss by finding the area of this triangle using the formula: 0.5 x base x height.
The Steinmetz equation is used to calculate iron losses in electrical machines like transformers and motors. It takes into account both hysteresis and eddy current losses. The equation is given as P_loss = KfB_max^1.6*V^2.2, where P_loss is the iron loss, K is a constant, f is the frequency, B_max is the maximum magnetic flux density, and V is the volume of the iron core.
No, diamagnetic materials do not exhibit hysteresis loss because they do not have permanent magnetic moments that can be aligned and re-aligned in response to an external magnetic field. Hysteresis loss occurs in ferromagnetic materials due to the energy dissipated during the reversal of magnetic domains.
To minimize hysteresis loss
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.
