Calculate magnetic induction at point O if the wire carrying a current I has the shape as shown in figure. (The radius of the curved part of the wire is equal to R and linear parts of the wire are very long.)

A current I flows along a round loop. Find the integral ∫B.dr along the axis of the loop within the range from (−∞) to (+∞). Explain the result obtained.
