V Part A Two long, straight wires are oriented perpendicular to the page, as shown in the figure(Figure 1). The current in one wire is /1 = 3.0 A, pointing into the page, and the current in What is the magnitude of the magnetic field at point P due to current /1? the other wire is 12 = 4.0 A, pointing out of the page.
