Part 5/6:
Looking ahead, the experimenter indicated plans to insert a FET rod inside the coil to achieve better tuning capabilities. Such modifications could fine-tune resonant frequencies, leading to more efficient power transfer. The current setup is described as a "quick and easy" configuration at a new location, marking the start from scratch compared to previous tests.
This iterative approach—testing, measuring, then refining—mirrors common best practices in experimental physics and electrical engineering, especially in the highly nuanced field of wireless energy transfer.
