Question

What is the effect of a larger cross-sectional area of the coils on mutual inductance?

Options

• No flux linkage and \[M=0\]

• More flux linkage and larger \[M\]

• A change in the SI unit of \[M\]

• Less flux linkage and smaller \[M\]

Answer 1

The size and geometry of the coils affect how much magnetic flux links them. A larger cross-sectional area gives more flux linkage and a larger mutual inductance.
