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 ...

Tesla coils are always a hit around here at the office. Giant ones that play music with modern-day chain mail wearing DJ’s, ones thrown together in garages by self-proclaimed mad scientists… But have ...

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 ...

For nearly a quarter of a century, a small group of Nikola Tesla faithful have gathered in Brockport, N.Y., just a few miles from where the Serbian electrical genius helped to engineer the world’s ...

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 ...

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 ...

You don’t have a Tesla coil? And you call yourself a mad scientist. You should take a lesson from electrical engineer Greg Leyh and build yourself a pair of 118-footers. That’ll show those fools who ...

If you have a newer-model smartphone it probably comes with built-in wireless charging. There's even talk of wireless charging coming to electric vehicles in the future. Image someday having a home ...
