Lagging of changes in the magnetization of a substance behind changes in the magnetic field as the magnetic field is varied is known as magnetic_____________?
Correct answer: D. Hysteresis
- A. Retaintivity
- B. Permeability
- C. Flux
- D. Hysteresis
Explanation
Hysteresis is the lag of magnetization or flux density behind the changing magnetizing field. Retentivity is only the residual magnetism left after the field is removed, so it is not the described phenomenon.
