Tessellate - S.T.E.M.S - Physics - School - Set 2 - Problem 2

Current $I$ is flowing along the edges of one face of a cube, as shown in Figure I, producing magnetic field $\vec{B}=B_o \vec{j}$ at the center of the cube. Now, in Figure II, consider another identical cube, where the current $I$ flows along the path shown.

What magnetic field exists at the center of the second cube?
