Which of the following produces a magnetic field?
Correct answer: D. All
- A. Orbital motion of electron
- B. Spin motion of electron
- C. Spin motion of nucleus
- D. All
Explanation
Both the orbital motion of electrons around the nucleus and the spin motion of electrons contribute to the generation of a magnetic field. The spin motion of the nucleus also contributes, but it is much weaker compared to the electron contributions.

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.
