Two long straight wires carrying 8 A of conventional current are connected by a three-quarter-circular arc of radius 0.035 m

(Figure 21.98). (The rest of the circuit is far enough away that it contributes little magnetic field in this region.) Electric

fields are also present in this region, due to charges not shown on the drawing. An electron is moving to the right with a
