A current  `I = 5.0 A` A  flows  along a thin wire  shaped as shwon in Fig. The radius  of a curved  part of the  wire  is equal  to `R = 120 mm`, the angle `2varphi = 90^(@)`. Find the magentic induction of the field  at the  point `O`. img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/IROD_V01_C03_E01_222_Q01.png" width="80%"
