👉 In physics, a hysteresis loop is a type of circuit element that can store energy in its resistance and then release it as heat. It is characterized by the fact that when current flows through the element, it creates a voltage difference across the element's resistance, which may be negative or positive depending on the direction of flow. When this voltage difference exceeds a certain threshold value, the loop will either stop heating up (inhibiting the next flow) or heat up (expanding the
