Part 3/8:
As the experiment progresses, the experimenter plays with a steel rod inserted into the setup. The rod acts as an induction tuning tool, allowing manipulation of the magnetic coupling and resonance conditions within the circuit. When the rod is fully inserted into the ground connection, the system reaches nearly 21 volts, close to the previous peak of 22 volts. The fluctuations in voltage—rising and falling by small margins—highlight the dynamic nature of the system during tuning.
