In an atom, the magnetic field exists due to
Correct answer: D. all
- A. orbital motion of electron
- B. spinning of proton
- C. spinning of electron
- D. all
Explanation
In an atom, the magnetic field exists due to various phenomena:The orbital motion of electrons generates a magnetic field.The spinning of electrons (electron spin) also produces a magnetic field.The spinning of protons contributes to the overall magnetic field of the atom. Thus, the magnetic field in an atom arises from the combined effects of electron orbital motion, electron spin, and proton spin.

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.
