and the diameters of the wire. The video below shows the machine going through its paces, with pretty neat and tidy results. Being such a tedious task, this is far from the first coil winder we ...

The simplest generator consists of just a coil of wire and a bar magnet. When you push the magnet through the middle of the coil, an electric current is produced in the wire. The current flows in ...

Sure, the high voltage can be dangerous, but the urge to build lots of coils is even worse. [Learnelectronics] shows how to build a slayer exciter using a 3D-printed core, and lots of wire of course.

The metal wire mesh fabric is available in unlimited widths and up to 40 feet in length, and can even be spliced together at the installation site. Cascade Coil’s high-quality architectural ...

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.

Wrap the 4-inch nail with a coil of 25 to 50 turns of the wire. Connect one end of the coil to one terminal of the knife switch. Connect the other terminal of the knife switch to the battery.
