Web9 okt. 2024 · We have already investigated that passing a current through a wire in a magnetic field causes a force to be exerted on it. The opposite is also true, and when a force is exerted on a wire a current is induced in the wire. This completely revolutionised the world because it meant that electricity could now be cheaper to produce. Web28 mrt. 2024 · As far as I know, since the current is DC, there is a magnetic field (since current is moving), but there is no electric field It is true in a certain sense, and under certain conditions, that a DC current through a wire creates a magnetic component of a electromagnetic field, but no electric component (*) of an electromagnetic field.
