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 ...

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.

Each non-magnetic core coil is made with 20μm (0.79mil) diameter PCOCC (Pure Copper by Ohno Continuous Casting) wire, hand-wound exactly eight times to create an innovative rectangular shape.

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 ...
