A long wire carrying a 5.0A current perpendicular to the xy-plane intersects the x-axis at x=-2.0 cm. A second, parallel wire carrying a 3.0A current intersects the x-axis at x=2.0 cm. At what point or points on the x-axis is the magnetic field zero, (a) if the currents are in the same direction (b) if the currents are in opposite directions.(adsbygoogle = window.adsbygoogle || []).push({});

B = (u * I)/(2Pi * d)?

Im not really sure how to do this :(
