Question 97 of 276

Two identical conducting wires $\mathrm{A O B}$ and $\mathrm{C O D}$ are placed at right angles to each other. The wire $\mathrm{AOB}$ carries an electric current $\mathrm{I_1}$ and $\mathrm{COD}$ carries a current $\mathrm{I_2}$ . The magnetic field on a point lying at a distance ' $\mathrm{d}$ ' from $\mathrm{O}$ , in a direction perpendicular to the plane of the wires $\mathrm{A O B}$ and $\mathrm{C O D}$ , will be given by

Show answer and solution

Answer: (A) $\frac{\mu_0}{2 \pi}\left(\frac{\mathrm{I}_1+\mathrm{I}_2}{d}\right)^{1 / 2}$

\frac{\mu_0 \mathrm{I}}{2 \pi \mathrm{d}} \sqrt{\left(\mathrm{I}_1^2+\mathrm{I}_2^2\right)}
