What is the difference between hysteresis loop and hysteresis loss?

Hysteresis loss is caused by the magnetization and demagnetization of the core as current flows in the forward and reverse directions. A hysteresis loop shows the relationship between the induced magnetic flux density (B) and the magnetizing force (H).

What is hysteresis loop?

: a cycle of alternating changes involving elastic, magnetic, or dielectric hysteresis also : the loop-shaped graph representing such a cycle.

What is hysteresis and its examples?

Hysteresis means slow to respond, lagging, a retardation of an effect when the forces that act upon a body are changed. In economics, it refers to the delayed effects of something. For example, as unemployment rises, people get used to a lower standard of living.

What is the difference between hysteresis loss & eddy current loss?

The most significant difference between the Eddy current and Hysteresis loss is that the eddy current loss occurs because of the relative motion between the conductor and the magnetic field. Whereas the hysteresis loss occurs because of the reversal of the magnetism.

What is the relation between B and H?

Magnetic field strength or filed intensity (H) is the amount of magnetising force. Magnetic flux density (B) is the amount of magnetic force induced on the given body due to the magnetising force H. The relation between B and H is, B = μH.

What is retentivity in hysteresis loop?

Retentivity – A measure of the residual flux density corresponding to the saturation induction of a magnetic material. In other words, it is a material’s ability to retain a certain amount of residual magnetic field when the magnetizing force is removed after achieving saturation.

What is retentivity and coercivity in hysteresis loop?

Retentivity: The property of the magnetic material to retain magnetism even in the absence of the magnetizing field is known as retentivity or remanence. Coercivity: The magnetizing field (H) needed to demagnetize the magnetic material completely is known as its coercivity.

What is thermal hysteresis?

The separation of the melting and freezing temperature is usually referred to as thermal hysteresis, and the temperature of ice growth is referred to as the hysteresis freezing point. The hysteresis is supposed to be the result of an adsorption of antifreeze proteins to the crystal surface.
