  2. Magnetic hysteresis - Wikipedia

    en.wikipedia.org/wiki/Magnetic_hysteresis

    The downward curve after saturation, along with the lower return curve, form the main loop. The intercepts h c and m rs are the coercivity and saturation remanence. Magnetic hysteresis occurs when an external magnetic field is applied to a ferromagnet such as iron and the atomic dipoles align themselves with it.

  3. Hysteresis - Wikipedia

    en.wikipedia.org/wiki/Hysteresis

    The curves form a hysteresis loop. 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 are ...

  4. Jiles–Atherton model - Wikipedia

    en.wikipedia.org/wiki/Jiles–Atherton_model

    This is one of the most popular models of magnetic hysteresis. Its main advantage is the fact that this model enables connection with physical parameters of the magnetic material. [2] Jiles–Atherton model enables calculation of minor and major hysteresis loops. [1] The original Jiles–Atherton model is suitable only for isotropic materials. [1]

  5. Coercivity - Wikipedia

    en.wikipedia.org/wiki/Coercivity

    Typically the coercivity of a magnetic material is determined by measurement of the magnetic hysteresis loop, also called the magnetization curve, as illustrated in the figure above. The apparatus used to acquire the data is typically a vibrating-sample or alternating-gradient magnetometer. The applied field where the data line crosses zero is ...

  6. Ferrimagnetism - Wikipedia

    en.wikipedia.org/wiki/Ferrimagnetism

    The downward curve after saturation, along with the lower return curve, form the main loop. The intercepts h c and m rs are the coercivity and saturation remanence. When ferrimagnets are exposed to an external magnetic field, they display what is called magnetic hysteresis, where magnetic

  8. Stoner–Wohlfarth model - Wikipedia

    en.wikipedia.org/wiki/Stoner–Wohlfarth_model

    In an ordinary magnetic hysteresis measurement, h starts at a large positive value and is decreased to a large negative value. The magnetization direction starts on the blue curve. At h = 0.5 the red curve appears, but for h > 0 the blue state has a lower energy because it is closer to the direction of the magnetic field. When the field becomes ...
