Vedclass · Answer

$\frac{\mathrm{R}_{1}}{\mathrm{R}_{2}}=\frac{\ell_{1}}{\ell_{2}}= \frac{\mathrm{I}_{2}}{\mathrm{I}_{1}}=\frac{	heta_{1}}{	heta_{2}} \Rightarrow 	heta_{1} \mathrm{I}_{1}=	heta_{2} \mathrm{I}_{2}$

$\left.\begin{array}{l}{\mathrm{B}_{1}=\frac{\mu_{0}}{4 \pi} \frac{\mathrm{I}_{1} 	heta_{1}}{\mathrm{r}}} \ {\mathrm{B}_{2}=\frac{\mu_{0}}{4 \pi} \frac{\mathrm{I}_{1} 	heta_{1}}{\mathrm{r}}}\end{array}ight\} \Rightarrow \mathrm{B}_{1}=\mathrm{B}_{2}$
