Mutually inductance between two magnetically-coupled coils depends on____________?
Correct answer: D. all of the above
- A. permeability of the core
- B. the number of their turns
- C. cross-sectional area of their common core
- D. all of the above
Explanation
Mutual inductance depends on core permeability, the turns of both coils, and their shared magnetic cross-sectional area, as reflected by M = k√(L₁L₂). Therefore all listed factors contribute.
