A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.

The optimized design actually uses the shape of the assembled component leads to act as the primary coil. The tiny Tesla coil isn’t big and bold enough to throw big sparks, but it will light a ...

The Tesla coil used for the demonstration is no slouch, either. It’s part of the Nevada Lightning Laboratory and can pack a serious punch (PDF warning). To receive the electrical energy from the ...

Renewable energy company INFRGY recently showcased a wireless energy system at Kashmir University, proving how Nikola Tesla's ...

Alzamend Neuro announced the completion of a device designed by Tesla Dynamic Coils, to monitor lithium levels in the brain, which will help researchers identify therapeutic target doses for a range ...
