Human utilization of energy is essentially a sophisticated art of transformation. The core principle of pedal-powered electricity generation is to convert the chemical energy of human muscles into the kinetic energy of a generator rotor through the mechanical movement of pedaling, which in turn cuts magnetic field lines to generate electricity. According to Faraday's law of electromagnetic induction, when a closed conductor moves in a magnetic field and cuts magnetic field lines, an induced current is generated. When the generated voltage is high enough, it is sufficient to break down the air insulation between the two poles, forming a spectacular electric arc discharge phenomenon, which we see as "electric sparks" or "lightning." The Jacob's Ladder utilizes this principle, allowing the electric arc to "climb" upwards as heated air pushes it through the gradually widening gap between the electrodes.
