Materials having permeability larger than one are:
Correct answer: C. Ferromagnetic
- A. Diamagnetic
- B. Paramagnetic
- C. Ferromagnetic
- D. None of these
Explanation
Ferromagnetic materials, like iron and nickel, have amagnetic permeability much greater than 1. This propertyallows them to be strongly magnetized and exhibit a strongattraction to magnetic fields.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
