In this lab, you can see the graph of the magnetic field on the x-axis as a function of position. Click-and-drag the wires to move them left or right. The wire on the left is confined to the region to the left of the origin; the wire on the right is confined to the region to the right of the origin. On the graph, the magnetic field is shown as positive if the net field at that position is directed up, and the field is shown as negative if the field is directed down. Using the sliders, you can adjust the values of the currents.
