Question

An infinite wire has a circular bend of radius a , and carrying a current I as shown in figure. The magnitude of magnetic field at the origin $O$ of the arc is given by :

Select the correct option:

$\frac{\mu_{0}}{4 \pi} \frac{I}{a}\left[\frac{3 \pi}{2}+2\right]$

$\frac{\mu_{0}}{4 \pi} \frac{I}{a}\left[\frac{3 \pi}{2}+1\right]$

$\frac{\mu_{0}}{4 \pi} \frac{I}{a}\left[\frac{\pi}{2}+1\right]$

$\frac{\mu_{0}}{2 \pi} \frac{I}{a}\left[\frac{\pi}{2}+2\right]$

✓ Correct! Well done.
