Inductors, coils and chokes are passive devices that are designed to resist changes in current and store energy in the form of a magnetic field. In their simplest form, inductors consist of a wire ...

Traditionally, the motor coils that produce the magnetic field are called “field coils” while the coils and the solid core are called the “armature." Generator coils are designed for use with ...

PCB motors are useful things. With coils printed right on the board, you don’t need to worry about fussy winding jobs, and it’s possible to make very compact, self contained motors.

[Zach Armstrong] presents for your viewing pleasure a simple guide to building a solid-state Tesla coil. The design is based around a self-resonant setup using the UCC2742x gate driver IC ...

Loov caught Nastasiuk with a vicious blindside hit to the head that landed Loov a major penalty and game misconduct. At 6-foot-3, 200 pounds, 22-year-old Toronto Maple Leafs prospect Viktor Loov ...

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.
