a–f Field-dependent reversal of Type I (red circle), Type II (blue square) and Type III (green triangle) in AMQs P2A, P2B, P2C, P3A, P3B, and P3C, respectively. g–l Total charge Qtot for P2A, P2B, P2C, P3A, P3B, and P3C, respectively. m–r Number of clockwise (CW) and counter-clockwise (CCW) flux-closure loops (FCLs) (see the insets in (m) and (p) for their definition) for P2A, P2B, P2C, P3A, P3B, and P3C, respectively. s–x Evaluation of relative amounts of maximum possible individual vertex charges Q in P2A, P2B, P2C, P3A, P3B, and P3C, respectively. The purple, dark yellow, and dark cyan colored symbols represent charges 3 (for N = 3), 4 (for N = 4), and 5 (for N = 5), respectively. The values in (s), (t) and (v) were multiplied by 3 for better visualization using a unique y scale for all graphs. Notice the presence of charges ∣Q∣ = 5 in P2C for N = 5 vertices. The error bars are calculated based on the number of nano bars below the noise level of the background (that is, the signal-to-noise ratio is below 1). The error bars in (m)–(r) are multiplied by five times for better comparison purposes.
