Hysteresis loss for steel is ……. .that for iron.

They hysteresis loss for a speciment of iron weighing 12 kg is equivalent to 300 J m^-3 cyc^-1 . Find the loss of energy per hour at 50 cycles s^-1 . Given, density of iron = 7,500 kg m^-3

The hysteresis loss for a specimen of iron weighing 15kg is equivalent at 300Jm^(-3)cycle^(-1) Find the loss of energy per hour at 25 cycle s^(-1) . Density of iron is 7500kg m^(-3)

What is meant by hysteresis? Discuss briefly the dissipation of energy due to hysteresis. Draw hysteresis curves to soft iron and steel.

Define retentivity and coercivity. Draw the hysteresis curve for soft iron and steel. What do you infer from these curves ?

What is meant by hysteresis loss? Where is the study of hysteresis used?

Explain hysteresis and draw hysteresis curve for a ferromagnetic substance.

The hysteresis loop of a soft iron piece has a much smaller area than that of a carbon steel piece. If the material is to go through repeated cycles of magnetisation, which piece will dissipate greater heat energy.
