In the figure two inifinitely long wires carry equal currents i. Each follows a 90∘ arc on the circumference of the same circle of radius R. Show that the magnetic field B→ at the center of the same as the field B a distance R below on infinite straight wire carrying a current i to the left.

A current is set up in a wire loop consisting of a semicircle of radius 4.00 cm, a smaller concentric semicircle, and two radial straight lengths, all in the same plane. Figure shows the arrangement but is not drawn to scale. The magnitude of the magnetic field produced at the center of curvature is 47.25μT.The smaller semicircle is then flipped over (rotated) until the loop is again entirely in the same plane. The magnetic field produced at the (same) center of curvature now has magnitude 15.75μT, and its direction is reversed from the initial magnetic field. What is the radius of the smaller semicircle?
