In the figure, two long straight wires at separation d = 6.22 cm carry currents of 1₁ = 4.25 mA and 1₂ = 3.00 1₁ out of the page. (a) At what coordinate on the x axis in centimeters is the net magnetic field due to the currents equal to zero? (b) If the two currents are doubled, is the zero-field point shifted toward wire 1, shifted toward wire 2, or unchanged? (a) Number i (b) unchanged ! Units d
