Question

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

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

Answer 1

Answer: (D)

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