NEET Physics Question - Magnetic Effects of Current - Magnetic Field Due to Circular Current Carrying Wire

A wire loop is formed by joining two sections of radii r1 and r2 subtending an angle θ at O. The magnetic field at O is B0. Image related to

\[B_{0}=\frac{\mu_{0}I}{4\pi}\left( \frac{1}{r_{1}}+\frac{1}{r_{2}} \right)\theta : outwards\]

\[B_{0}=\frac{\mu_{0}I}{4\pi}\left( \frac{1}{r_{1}}-\frac{1}{r_{2}} \right)\theta : inwards\]

\[B_{0}=\frac{\mu_{0}I}{2\pi}\left( \frac{1}{r_{1}}+\frac{1}{r_{2}} \right)\theta : outwards\]

\[B_{0}=\frac{\mu_{0}I}{2\pi}\left( \frac{1}{r_{1}}-\frac{1}{r_{2}} \right)\theta : inwards\]
