Question:

In Figure, a conductor carries 6.0 A along the closed path abedefgha running along 8 of the 12 edges of a cube of edge length 10 cm.
(a) Taking the path to be a combination of three square current loops (befgb, abgha, and cdefc), find the net magnetic moment of the path in unit-vector notation.
(b) What is the magnitude of the net magnetic field at the xyz coordinates of (0, 5.0 m,0)?
