Physics - Magnetism Question with Solution | TestHub

Two fixed infinitely long straight conductors are kept perpendicular to each other as shown in figure. Here ${\mathrm{I}}_1=20\mathrm{A}$ along +ve Y-axis and ${\mathrm{I}}_2=30\mathrm{A}$ along -ve z -axis. It is given that $\mathrm{AP}=\mathrm{AB}=1\mathrm{cm}$. The value of magnitude of magnetic field strength $\overrightarrow{\mathrm{B}}$ at P is $\mathrm{m}\times 10^{-\mathrm{n}}\mathrm{T}$. Find the value of (m+n).
