Solution

The correct option is B $\frac{μ_{0} I}{4} (\frac{r_{1} + r_{2}}{r_{1} r_{2}})$ into the page
$| B_{1} | = \frac{μ_{0} I}{4 r_{1}}$ into the plane
$| B_{2} | = \frac{μ_{0} I}{4 r_{2}}$ into the plane
Net $| B_{1} | = \frac{μ_{0} I}{4} \times (\frac{r_{1} + r_{2}}{r_{1} r_{2}})$ into the plane
