Two coils are placed close to eachother. The mutual inductance of the ...
Explanation:

Mutual inductance is defined as the ability of one coil to induce an electromotive force (EMF) in another coil due to the changing magnetic field produced by the first coil. It depends on the following factors:

1. Relative position and orientation of the two coils:
- The mutual inductance between two coils is maximum when they are placed in close proximity to each other.
- The orientation of the coils also plays a crucial role in determining the mutual inductance. If the coils are parallel to each other, the mutual inductance is maximum. If they are perpendicular to each other, the mutual inductance is minimum.

2. Number of turns in the coils:
- Mutual inductance is directly proportional to the number of turns in the coils. More the number of turns, greater is the mutual inductance.

3. The current in the coils:
- The mutual inductance between two coils is proportional to the current flowing through them. Higher the current, greater is the mutual inductance.

4. The materials of the wires of the coils:
- The mutual inductance also depends on the materials used for making the coils. Materials with high magnetic permeability, like iron or ferrite, have a greater mutual inductance than materials with low permeability, like copper or aluminum.

Therefore, the correct answer is option 'B', as the relative position and orientation of the two coils play the most significant role in determining the mutual inductance between them.
