Q. A toroid with thick windings of $N$ turns has inner and outer radii $R_{1}$ and $R_{2}$ respectively. If it carries certain steady current I, the variation of the magnetic field due to the toroid with radial distance is correctly graphed in

$B = μ_{0} n I$
where $n = \frac{N}{2 π r}$
$B = \frac{μ _{0} N I}{2 π ( \frac{R _{1} + R _{2}}{2} )}$
$B = \frac{μ _{0} N I}{π ( R _{1} + R _{2} )}$
