This is called electromagnetic induction close electromagnetic inductionThe production of a potential difference (voltage) when a conductor, such as a wire, is moved through a magnetic field or ...

The Biot-Savart law states that an electrical current flowing through a wire will generate a magnetic field around itself represented by vectors that twist around like a vortex.

The induced voltage produces an induced current if the conductor is connected in a complete circuit. As with all currents, the induced current creates a magnetic field around itself. Note that ...

This magnetic field can then induce an electric field in any nearby neurons—the same effect created by an electrode but much more precise. However, this technique comes with a major downside.

A generator is simply a device that converts mechanical energy (itself derived from coal, oil, natural gas, wind, water, nuclear reactions or other sources) into electrical energy. Here, we ...
