Physics - Magnetism Question with Solution | TestHub

The magnetic field in between because of each will be in opposite direction $$\begin{array}{rl}{B}_{\text{in between }}& =\frac{{\mu }_{0}i}{2\pi x}\hat{j}-\frac{{\mu }_{0}i}{2\pi (2d-x)}(-\hat{j})\\ & =\frac{{\mu }_{0}i}{2\pi }\left[\frac{1}{x}-\frac{1}{2d-x}\right](\hat{j})\end{array}$$ at $x=d,B_{\text{in between }}=0$ for $x<d,B_{\text{in between }}=(\hat{j})$ for $x>d,B_{\text{in between }}=(-\hat{j})$ towards $\mathrm{x}$ net magnetic field will add up and direction will be $(-\hat{\mathrm{j}})$ towards ${\mathrm{x}}^{\prime }$ net magnetic field will add up and direction will be $(\hat{\mathrm{j}})$
