We’ve gone full-nerd with high-voltage experimentation—bringing together a laser bazooka and a Tesla coil gun to see which one delivers the biggest zap. Watch live demos, safety breakdowns ...

IT is only within the last few years that the induction coil has emerged from the sanctum of the philosophical instrument maker and even approximated to an electrical engineering “job.” It ...

The coil gun could eventually have applications in areas such as weapon systems, near-earth satellites and high-speed missile launches. The Chinese military’s 30-stage coil gun is still in the testing ...

Recent advances in coil design have focused on optimising efficiency while reducing unwanted effects such as acoustic noise, excessive heating and peripheral nerve stimulation (PNS).
