A lot of time was spent to complete this demonstration.
For instance, he spent quite a bit of time on processing the magnetite into magnets and shaping them into the desired form.
Then came the task of making a wooden frame and winding coils around it, which took a little over a day each.
The ends of the coils were connected to an electric brush, with each brush tightly in contact with a metal ring.
Chen Chen spent a day crafting the brushes and copper rings.
Making the homemade filament didn't take long, but he felt there were structural and shape issues that needed adjusting once powered on.
Additionally, there was a problem with the copper wire shining brightly in the air when electrified, which meant it would quickly burn out and become useless.
But there was no need to worry about these details for the first demonstration.
For now, he just wanted the primitives to see what electricity was all about.
