Unicode Version 17.0
⎎
U+238E "⎎" Hysteresis Symbol is a specialized graphical character used primarily in technical diagrams and control system schematics to represent the phenomenon of hysteresis, where a system's output depends on its history of inputs, such as the classic lag between a magnetic field and its material response. It visually depicts a loop or a stylized shape that conveys the concept of a delayed or non-reversible reaction, often appearing in electrical engineering contexts like relay circuits or comparator designs. This symbol is part of the Miscellaneous Technical Unicode block and provides a standardized way to annotate documentation without relying on custom images, ensuring clarity across different software and platforms.
