• 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.
• Such a system is called hysteretic.
• 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 another variable.
