HystereseVerhalten

HystereseVerhalten, often translated as hysteresis behavior, describes a phenomenon where the state of a system depends not only on its current input but also on its past inputs. This means the system's response to an increasing input differs from its response to a decreasing input. The characteristic feature of hysteresis is a loop in the output versus input graph, known as the hysteresis loop.

This behavior arises when a system possesses some form of memory or when energy dissipation occurs. For example, in magnetic materials, the magnetization of a ferromagnetic substance does not immediately follow the applied magnetic field. It lags behind, retaining some magnetization even when the field is removed, and requires a reverse field to demagnetize it. This lag is due to the irreversible changes in magnetic domains within the material.

Hysteresis is observed in various scientific and engineering fields. It's crucial in understanding the operation of magnetic memory devices, the behavior of certain electronic components like relays and Schmitt triggers, and in the study of material science, particularly in the context of elasticity and plasticity. The width and shape of the hysteresis loop provide valuable information about the system's properties, such as the energy loss during a cycle and the residual state. Understanding hysteresisVerhalten is essential for accurate modeling and control of systems exhibiting this characteristic.
