WebNov 23, 2024 · The hysteresis effect is a phenomenon that occurs when the magnetization of ferromagnetic materials lags behind the magnetic field. The word hysteresis means “lagging.” Magnetic flux density (B) lags after magnetic field strength, resulting in hysteresis (H). Hysteresis is a property of all ferromagnetic materials. WebIron loss is further divided into hysteresis and eddy current loss. Hysteresis Loss.
