hüsteresiisi

Hüsteresiisi is a Finnish term that translates to hysteresis in English. Hysteresis refers to the phenomenon where the state of a system depends on its history. More specifically, it describes a situation where the output of a system lags behind the input, and the path taken by the input to reach a certain point is different from the path taken when the input is reversed.

This concept is observed in various scientific and engineering fields. In physics, hysteresis is commonly seen in magnetic materials. When a magnetic field is applied to a ferromagnetic material, the material becomes magnetized. However, when the applied field is removed, the material retains some of its magnetism, a phenomenon known as remanence. The relationship between the applied magnetic field and the magnetization of the material forms a hysteresis loop.

In economics, hysteresis can describe how certain economic variables, like unemployment, can be affected by past events. For instance, prolonged periods of high unemployment can lead to a loss of skills and a decrease in labor force participation, making it harder for individuals to find jobs even after the initial economic downturn has passed.

The term hysteresis is also used in psychology and biology, referring to the persistence of a state or behavior even after the original stimulus has been removed or changed. Understanding hysteresis is crucial for analyzing and predicting the behavior of systems that exhibit path dependence.
