8. The drawing shows an end-view of two wires. They are long, straight, and perpendicular to the plane of the paper. Their cross sections lie at the corners of a rectangle (a = 5.50 m, b = 17.5 m). The currents are oriented as shown in the figure (I1 = 18.0 A, I2 = 9.00 A). What is the magnitude of the magnetic field at bottom left corner? T b a mam 1 162 9. Two long, straight wires are separated by distance, d = 22.0 cm. The wires carry currents of I1 = 3.00 A and 12 = 8.00 A in opposite directions, as shown in the figure. I ma the mayin the net magnetic field at point (C). Let ri = 14.0
