Instead of using an electrode, Saha and her team turned to magnetic coils of wire. Over two centuries ago, physicist Michael Faraday described how electric current running through a coil of wire ...

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.

Even with the kinds of coils used in chokes and transformers ... The idea is to pass a small spool of magnet wire through the toroid’s core while simultaneously rotating the toroid to spread ...

Since the cook surface uses magnetic fields to generate heat in ... of a name for himself involving project that use various coils of wire, too, like this project we featured recently which ...

New-generation motors and coils are designed to be smaller, lighter, and more efficient, reducing the space available for wire windings. As a result, aluminum magnet wires, which take up more ...
