Diamagnetic substances are
Correct answer: C. Feebly repelled by magnets
- A. Feebly attracted by magnets
- B. Strongly attracted by magnets
- C. Feebly repelled by magnets
- D. Strongly repelled by magnets
Explanation
Diamagnetic substances are materials that create an induced magnetic field in a direction opposite to an externally applied magnetic field and are thus feebly repelled by the magnetic field. This is due to the paired nature of electrons in diamagnetic materials, which means there is no net magnetic moment. Option C is correct because it accurately describes this behaviour. Options A and B describe paramagnetic and ferromagnetic materials, respectively, which are attracted to magnets. Option D is incorrect because no substantial repulsion occurs in diamagnetic materials.

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.
