Question

The magnetic flux ($\varphi$) linked with a coil is related to the number (n) of turns of the coil as

• A. $\varphi \propto n^2$
• B. $\varphi \propto n^{-2}$
• C. $\varphi \propto n^{-1}$
• D. $\varphi \propto n$

Answer 1

Answer: (D)

$\varphi =n\overrightarrow{B}.\overrightarrow{A}$. And $B\propto n$.
