Which one of the following is paramagnetic material?
Correct answer: D. All of these
- A. Mg
- B. Li
- C. Titanium
- D. All of these
Explanation
The correct answer is All of these because Magnesium (Mg), Lithium (Li), and Titanium all have unpaired electrons, making them paramagnetic. Paramagnetic materials are characterised by their attraction to external magnetic fields due to these unpaired electrons. While each element demonstrates varying degrees of paramagnetism, they all possess the fundamental property of having unpaired electrons, which is essential for paramagnetism.

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.
