The relative permeability is less than unity is case of_____________?
Correct answer: D. diamagnetic materials
- A. ferromagnetic materials
- B. ferrites
- C. non-ferrous materials
- D. diamagnetic materials
Explanation
Diamagnetic materials have relative permeability slightly below unity because they weakly oppose an applied magnetic field. Ferromagnetic and ferrite materials have relative permeability much greater than unity.
