This phenomenon exists in any system where outputs are not a pure function of inputs, as seen on a graph of magnetization versus applied magnetic field in a ferromagnet when an alternating field is applied.
An operator that induces this phenomenon must be deterministic and rate-independent. The Preisach model conceptualizes this phenomenon as a collection of weighted nonideal relays connected in parallel. A transducer will exhibit this phenomenon if it has nontrivial internal states. A comparator can be made resistant to noise by augmenting it with this nonlinear property, converting it into a Schmitt trigger. This phenomenon exists in any system where outputs are not a pure function of inputs, as seen on a graph of magnetization versus applied magnetic field in a ferromagnet when an alternating field is applied. For 10 points, identify this strongly nonlinear phenomenon found in many magnetic systems, in which the system's state depends on its history.
