I-left = amps
I-right = amps       

Two wires are carrying the specified currents into or out of the plane of the simulation as shown above (OUT=RED, IN=BLUE).   You can drag both the compass and the wires.   Try unequal currents, and see if you can find a "zero" magnetic field along the axis.       Reset
