In Fig. 29-76a, two circular loops, with different currents but the same radius of 4.0 cm, are centered on a y axis. They are initially separated by distance L = 3.0 cm, with loop 2 positioned at the origin of the axis. The currents in the two loops produce a net magnetic field at the origin, with y component B_y. That component is to be measured as loop 2 is gradually moved in the positive direction of the y axis. Figure 29-76b gives B, as a function of the position y of loop 2. The curve approaches an asymptote of B_y = 7.20 µT as y →∞. The horizontal scale is set by y_s = 10.0 cm. What are (a) current i₁ in loop 1 and (b) current i₂ inloop2?
