A long, straight wire with a current of 7 amps runs in the -z direction through the origin. Another long straight wire has a current running in the +z direction on y axis at y = +3 meters. A charge of -8 coulombs is moving at 27 m/s in the +y direction at x = 0 m, y = -0.6 meters. Due to the total magnetic field from both wires at that point, the magnetic force on the charge is 26 x 10-7 Newtons in the +z direction. What is the amount of the current of the second wire in amps?
