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.

The area of hysteresis loop in a ferromagnetic material of?

The area of the hysteresis loop in a ferromagnetic material represents the energy losses that occur during the magnetization and demagnetization processes. It is a measure of the energy dissipated as heat due to the magnetic domain reorientation within the material. The larger the area of the hysteresis loop, the greater the energy losses and the lower the efficiency of the material in applications such as transformers or inductors.


Does a diamagnetic substance exhibit hysteresis loss?

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.


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.


Why core loss depends on voltage?

Core loss depends on voltage because it is primarily due to hysteresis and eddy current losses in the magnetic core material. When the voltage increases, it leads to higher magnetic flux density variations within the core material, causing an increase in hysteresis and eddy current losses, thus resulting in higher core losses.


In a magnetic material hysteresis loss can't be reduce to zero Why?

In normal ferromagnetic material, the magnetic domains within the material are randomly oriented. When an external magnetic field is applied, it causes the magnetic domains to align more or less in the same direction. During the second half of the AC cycle, when flux is flowing the opposite direction, extra energy is required to flip those domains all the way around to face the other direction. And then, in the first half of the next AC cycle, they have to flip all the way around again. That extra energy is the hysteresis loss.

What is hysteresis loss?

If the magnetic field applied to a magnetic material is increased and then decreased back to its original value, the magnetic field inside the material does not return to its original value. The internal field 'lags' behind the external field. This behaviour results in a loss of energy, called the hysteresis loss, when a sample is repeatedly magnetized and demagnetized. The materials used in transformer cores and electromagnets are chosen to have a low hysteresis loss. Similar behaviour is seen in some materials when varying electric fields are applied (electric hysteresis). Elastic hysteresis occurs when a varying force repeatedly deforms an elastic material. The deformation produced does not completely disappear when the force is removed, and this results in energy loss on repeated deformations.


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.


How do you minimize core losses?

Hysteresis and eddy current loss constitute core loss. It can be reduced by replacing solid core by laminated core... by adeeb
