The Magnetic Hysteresis loop above, shows the behaviour of a ferromagnetic core graphically as the relationship between B and H is non-linear. Starting with an unmagnetised core both B and H will be at zero, point 0 on the magnetisation curve. If the magnetisation current, i is … Visa mer Previously, the relative permeability, symbol μr was defined as the ratio of the absolute permeability μ and the permeability of free … Visa mer By plotting values of flux density, ( B ) against the field strength, ( H ) we can produce a set of curves called Magnetisation Curves, Magnetic Hysteresis Curves or more commonly B-H Curves for each type … Visa mer However, the magnetic flux does not completely disappear as the electromagnetic core material still retains some of its magnetism even when the current has stopped flowing in the coil. This ability for a coil to … Visa mer The set of magnetisation curves, M above represents an example of the relationship between B and H for soft-iron and steel cores but every type of core material will have its own set of magnetic hysteresis curves.

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 different values of one variable depending on the direction of change of an… WebbThe shape of a hysteresis loop can be diagnostic of the mineralogy of the sample (Channell and McCabe, 1994; Tauxe, 1993). Ferrimagnetic minerals tend to produce narrow loops, whereas the presence of antiferromagnetic minerals causes hysteresis loops to be wider. What Does The Area Of A Hysteresis Loop Represent?
