physics : a retardation of an effect when the forces acting upon a body are changed (as if from viscosity or internal friction)

Example Sentences
Recent Examples on the Web Economists borrowed the term hysteresis from the physics of magnetism. Jon Hilsenrath, WSJ, 25 Feb. 2021 For many years, economists have looked for evidence of hysteresis in labor markets. Jon Hilsenrath, WSJ, 25 Feb. 2021 But their data suggested that hysteresis was still happening. Siobhan Roberts, New York Times, 17 Mar. 2020 There’s some heated (so to speak) debate about what really causes hysteresis. Caroline Delbert, Popular Mechanics, 22 Apr. 2020 These objects become permanently magnetized, through a process called hysteresis. Jennifer Leman, Popular Mechanics, 7 Dec. 2019 Paleoclimatologists said this hysteresis might explain other puzzles about the paleoclimate record. Natalie Wolchover, WIRED, 3 Mar. 2019 See More
