Part 7/8:
Tightening the coil tends to reduce the detectable AC voltage, while loosening and repositioning can increase it.
The physical orientation and distance from ground influence measurement values, demonstrating the delicate balance in electromagnetic interactions.
The environment’s "no circuit" condition yields minimal voltages, yet the presence of coils and the physical adjustments cause measurable variations.
Conclusion
Paul’s hands-on testing illustrates important principles in electromagnetic experimentation: that physical positioning, tension, and proximity significantly influence observed AC voltages. His approach emphasizes the importance of meticulous adjustments when working with coils and antennas, especially in open-field or experimental setups.
