Subtopic: Magnetic Field Due to Straight Current Carrying Wire
A wire carrying current I has the shape as shown in adjoining figure. Linear parts of the wire are
very long and parallel to X-axis while semicircular portion of radius R is lying in Y-Z plane. Magnetic field at point O is :
\[\overrightarrow{B}=-\frac{\mu_{0}}{4\pi}\frac{I}{R}\left( \pi \hat{i}-2\hat{k} \right)\]
\[\overrightarrow{B}=-\frac{\mu_{0}}{4\pi}\frac{I}{R}\left( \pi \hat{i}+2\hat{k} \right)\]
\[\overrightarrow{B}=\frac{\mu_{0}}{4\pi}\frac{I}{R}\left( \pi \hat{i}-2\hat{k} \right)\]
\[\overrightarrow{B}=\frac{\mu_{0}}{4\pi}\frac{I}{R}\left( \pi \hat{i}+2\hat{k} \right)\]
