HYSTERESIS LOOP Meaning and
Definition
-
Hysteresis loop refers to the graphical representation of the relationship between two variables, typically input and output, in a dynamic system where the output does not immediately respond to changes in the input. It is a characteristic feature of systems or materials that exhibit hysteresis.
In physics and engineering, hysteresis loop describes the phenomenon where the output of a system lags behind changes in its input, resulting in a closed loop-shaped graph when plotted. Such systems possess memory or a delay in their response to changes in the input. The hysteresis loop illustrates the relationship between the current state and the history of the system, showcasing the dependence of the output on past values of the input variable.
The loop represents the complete cycle of the system's response, starting from an initial state through a series of varying inputs and outputs and returning back to the initial state. The loop shape may vary depending on the specific characteristics of the system or material. It typically shows a lag or delay in the response as the input variable is decreased or increased.
Hysteresis loops are commonly observed in various fields, including electrical engineering, materials science, economics, and biology. They are particularly significant in the study of magnetic materials, where the hysteresis loop represents the relationship between the magnetic field strength (input) and the magnetization (output) of the material. Understanding and analyzing hysteresis loops is essential in designing and optimizing systems that exhibit hysteresis behavior.

Etymology of HYSTERESIS LOOP
The word "hysteresis" is derived from the Greek words "hysterein" (ὑστερεῖν) meaning "to be late, fall short" and "hysteron" (ὕστερον) meaning "later". It was first used in the mid 19th century by Sir James Alfred Ewing, a British physicist, to describe the phenomenon of lagging or delayed magnetization.
The term "hysteresis loop" is a combination of "hysteresis" and "loop". "Loop" refers to the graphical representation of the phenomenon on a graph, where the relationship between input and output is plotted as a closed loop.
