Part 6/9:
Using a steel ball bearing at the bottom of a bucket, he carefully drops the bulb, aiming to dislodge it gently. Despite his precautions, parts of the winding come loose, and some windings are lost or damaged, leading to disappointment. Nonetheless, he manages to retrieve the coil, hoping that some windings still remain intact for testing.
Results and Lessons Learned
Preparing to power the coil with AC current, Paul sets up the experiment, placing a hollow aluminum ball inside the spherical coil. As he energizes the system with a modest number of windings (around 160), the coil seemingly bounces and vibrates. He notices a strange smell, possibly burning insulation or superglue, and the coil begins to collapse or behave unpredictably.
