Electric current is often magic and mysterious. Before people knew about electricity, many natural phenomena appeared as supernatural events caused by angry gods. Fortunately people today know physics ...

Arguably, the most tedious part of any Tesla coil build is winding the transformer. Getting that fine wire wound onto a suitable form, making everything neat, and making sure it’s electrically and ...

Like so many of the projects we feature, this one started with a cheap eBay module purchase. In this case, it was a little Tesla coil that made decent sized arcs but wasn’t quite good enough. The ...

The role of J.P. Morgan in getting Tesla's Tower built. The fundamental operation of a Tesla coil. Dealing with EMI generated by a Tesla coil. When I lived in Long Island, N.Y., I had a most ...

Using a powerful electric force emitted by a Tesla coil, scientists at Rice University have made carbon nanotubes self-assemble to form a circuit linking two LEDs and then used the energy from that ...

The ancient Greek god Zeus was said to be able to throw lightning bolts; Nikola Tesla emulated this with his Tesla coil design on a grand scale. But is this device a great invention, a novelty or just ...

This “pancake” inductor wound with copper tubing forms the primary of the Tesla coil. The heavy black wire connects to an adjustable “tap” that allows tuning of the primary circuit. The elevated ...
