When the magnetic field strength is reduced towards zero, the resulting change in flux density tends to lag behind, due to a property called
A) remenance
B) saturation
C) coercivity
D) hysteresis

Question

Quizplus · Accepted Answer

Hysteresis is a property of magnetic materials where the magnetic flux density lags behind changes in the magnetic field strength, creating a loop or hysteresis curve when plotted on a graph. This phenomenon is a result of the energy required to change the alignment of magnetic domains within the material and can cause the material to retain magnetization even when the magnetic field is removed, known as remanence. Saturation and coercivity are related properties but do not fully explain the lag in flux density changes.
