Question

How does increasing the number of turns \[N_1\] and \[N_2\] affect mutual inductance?

Options

• \[M=0\] whenever both coils have turns.

• \[M\] increases as turns increase; \[M\propto N_1N_2\].

• \[M\] decreases as turns increase; \[M\propto 1/(N_1N_2)\].

• \[M\] is independent of both \[N_1\] and \[N_2\].

Answer 1

More turns increase the total flux linkage between the coils. The stated dependence is \[M\propto N_1N_2\] .
