Influence of Conductive and Ferrous Materials
Further experiments involve inserting different materials—such as copper rods and ferrous rods—into the setup. Paul observes that inserting a copper rod causes the voltage to drop swiftly, even when the rod is carefully positioned close to the wall. The voltage readings diminish "real fast" upon insertion, revealing that introducing conductive material inside the coil impacts the energy transfer or field interaction.
Similarly, when a ferrous rod is inserted, a comparable effect is observed. These results suggest that the electromagnetic coupling is highly sensitive to the materials placed within the coil's vicinity, affecting the energy transfer efficiency or magnetic resonance.
