Question
A long wire carrying a 6.0 A current perpendicular to the xy-plane intersects the x-axis at x=−2.0cm. A second, parallel wire carrying a 2.0 A current intersects the x-axis at x=+2.0cm. At what point on the x-axis is the magnetic field zero if the two currents are in the same direction?
At what point on the x-axis is the magnetic field zero if the two currents are in opposite directions?
