On the other … WebMagnetic fields have both direction and magnitude. As noted before, one way to explore the direction of a magnetic field is with compasses, as shown for a long straight current-carrying wire in Figure 1. Hall probes can determine the magnitude of the field. The field around a long straight wire is found to be in circular loops. cey yecla WebSep 12, 2024 · From these results, it is not surprising that copper is used for wires for carrying current because the resistance is quite small. Note that the current density and …
