Substances which have permeability less than the permeability of free space are known as_____________?
Correct answer: C. diamagnetic
- A. ferromagnetic
- B. paramagnetic
- C. diamagnetic
- D. bipolar
Explanation
Diamagnetic substances oppose an applied magnetic field and have permeability lower than the permeability of free space, so μᵣ < 1. Ferromagnetic and paramagnetic materials have relative permeability greater than unity.
