A long wire carrying a 4.0A current perpendicular to the xy -plane intersects the x -axis at x= -2.3cm. A second, parallel wire carrying a 2.6A current intersects the x -axis at x= +2.3cm
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 the opposite direction?
