Two wires separated by a distance of 22 cm carry currents in the same direction. The current in one wire is I1 = 1.5 A , and the current in the other wire is I2 = 4.5 A The current is adjusted until the magnetic field halfway between the wires has a magnitude of 2.7×10−6 T and points into the page. Everything else in the system remains the same. Find magnitude of I1
u.I1/2.pi.r -u.I2/2.pi.r u = permeability r = 22/2
