Physics

An infinitely long straight wire carrying current I is bent in a planer shape as shown in the diagram. The radius of the circular part is r . The magnetic field at the centre O of the circular loop is :

\\

\frac{\mu_{0}}{2 \pi} \frac{\mathrm{I}}{\mathrm{r}}(\pi+1) \hat{\mathrm{i}}

-\frac{\mu_{0}}{2 \pi} \frac{\mathrm{I}}{\mathrm{r}}(\pi-1) \hat{\mathrm{i}}

\frac{\mu_{0}}{2 \pi} \frac{\mathrm{I}}{\mathrm{r}}(\pi-1) \hat{\mathrm{i}}

-\frac{\mu_{0}}{2 \pi} \frac{\mathrm{I}}{\mathrm{r}}(\pi+1) \hat{\mathrm{i}}
