Physics Question on Magnetic Field
Two coils are placed close to each other. The mutual inductance of the pair of coils depends upon
A
the rates at which current are changing in the two coils
B
relative position and orientation of the two coils
C
the materials of the wires of the coils
D
the currents in the two coils
Answer
the materials of the wires of the coils
Explanation
Solution
The mutual inductance of the pair of coils depends on geometry of two coils, distance between two coils, distance between two coils, relative placement of two coils etc.
