Problem 17
Consider the following current loops, which have the same current I in every loop. Rank the following cases based on the magnitude of the total magnetic field at the center of the loops, greatest first
a) 5, 1 = 3, 2, 4
b) 2, 4, 5, 1 = 3
c) 3 = 1, 4, 5 = 2
d) 4, 2, 3 = 1, 5
e) 1 = 3, 5, 4, 2
