Problem 3.226
Find the magnetic induction of the field at the point \(O\) if a current-carrying wire has the shape shown in Fig. \(3.62 a, b, c .\) The radius of the curved part of the wire is \(R,\) the linear parts are assumed to be very long.
3.226. (a) \(B=\left(\mu_{0} / 4 \pi\right)(\pi I / R)\) (b) \(B=\left(\mu_{0} / 4 \pi\right)(1+3 \pi / 2) I / R\) (c) \(B=\left(\mu_{0} / 4 \pi\right)(2+\pi) I / R\)
