The area of hysteresis loop is a measure of
WebA family of hysteresis loops for grain-oriented electrical steel, a soft magnetic material. BR denotes retentivity and HC is the coercivity. The wider the outside loop is, the higher the coercivity. Movement on the loops is counterclockwise. Coercivity, also called the magnetic coercivity, coercive field or coercive force, is a measure of the ... WebApr 12, 2024 · The shape of hysteresis loops is characteristic of a ferromagnetic state, even in the mixed powder. For the samples sintered at 600–980 °C, the observation of a “hard” loop (strong magnetic coercive field) coupled with a small value of magnetization also confirms that the magnetization is an induced one and has its origin due to the canting of …

The energy losses E at running through a single hysteresis loop can be determinate. As a last calculation the dissipation Ph(t) owing to the hysteresis losses at a frequency f of 100 kHz. Hysteresis is the dependence of the state of a system on its history. For example, a magnet may have more than one possible magnetic moment in a given magnetic field, depending on how the field changed in the past. Plots of a single component of the moment often form a loop or hysteresis curve, where there … See more The term "hysteresis" is derived from ὑστέρησις, an Ancient Greek word meaning "deficiency" or "lagging behind". It was coined in 1881 by Sir James Alfred Ewing to describe the behaviour of magnetic materials. See more Elastic hysteresis In the elastic hysteresis of rubber, the area in the centre of a hysteresis loop is the energy dissipated due to material internal friction. Elastic hysteresis was one of the first types of hysteresis … See more Cell biology and genetics Hysteresis in cell biology often follows bistable systems where the same input state can lead to two different, stable outputs. Where bistability can lead to digital, switch-like outputs from the continuous inputs of … See more Rate-dependent One type of hysteresis is a lag between input and output. An example is a sinusoidal input … See more Control systems In control systems, hysteresis can be used to filter signals so that the output reacts less rapidly than it otherwise would by taking recent … See more Magnetic hysteresis When an external magnetic field is applied to a ferromagnetic material such as iron, the atomic domains align themselves with it.
