A long, straight wire, carrying a current of 200 A, runs through a cubical wooden box, entering and leaving through holes in the centers of opposite faces (see the figure (Figure 1) ). The length of each side of the box is 20.0 cm. Consider an element dl of the wire 0.100 cm long at the center of the box. (Note: Assume that dl is small in comparison to the distances from the current element to the points where the...
