14. We refer to the side of length L as the long side and that of length W as the short side. The center is a distance W/ 2 from the midpoint of each long side, and is a distance L/ 2 from the midpoint of each short side. There are two of each type of side, so the result of problem 11 leads to B =2 µ 0 i 2 π ( W/
