... brought into the vicinity of a current carrying wire. Thus, currents can induce a magnetic field. An electromagnet is simply a coil of wires which, when a current is passed through, generate a magnetic field, as below. Current gives rise to magnetic fields, just as electric charge gave rise to elect ...

... Some rocks carry current better than others. Igneous rocks do not conduct electricity very well so the currents tend to take the path of least resistance and flow through man-made conductors that are present on the surface (like pipelines or cables). Regions of North America have significant amounts ...
