Question

Two coils are placed close to each other. The mutual inductance of the pair of coils depends upon ______.

विकल्प

• the rates at which currents are changing in the two coils.

• relative position and orientation of the two coils.

• the materials of the wires of the coils.

• the currents in the two coils.

Answer 1

Two coils are placed close to each other. The mutual inductance of the pair of coils depends upon relative position and orientation of the two coils.

Explanation:

Mutual inductance is a geometric property that measures how effectively magnetic flux from one coil links with another. Factors such as the distance between the coils and their orientation angle directly determine the degree of flux linkage, thereby changing the mutual inductance. While the rate of current change affects the magnitude of the induced EMF, it does not change the mutual inductance constant itself.
