5. Estimate the change in flux for one of your results in Table 1. Note: Resistance of a wire is equal to pL/A and the resistivity of copper is 1.68 x 10-8 Qm. The diameter for the wire should be given on the kit packing list, for example, "24AWG" = "24 American Wire Gauge". (In AWG, the larger the number, the smaller the wire diameter and thickness.) If you Google "24AWG" you can get the AWG diameter: 0.0201 inches = .00051 meters. So, your radius would be .00025 m or 2.5E-4 m.
