Materials with permeability less than 1 are:
Correct answer: A. Diamagnetic
- A. Diamagnetic
- B. Ferromagnetic
- C. Paramagnetic
- D. All of these
Explanation
Diamagnetic materials have a magnetic permeability slightlyless than 1. This causes them to create a weak magnetic fieldin opposition to an external field, resulting in weak repulsion.

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.
