Magnet wire Code: MAGNETWIRE Price: $8.73 Quantity in Basket: none Sixty feet of 22 gauge polyurethane coated copper wire. The green insulation is easy to distinguish from the bare copper, so it is easy to scrape off just the right amount when building the Simple Motor project. Also great for winding the antenna coil of the Portable Crystal Radio, and the perfect length for an antenna for the Simple Crystal Radio project. This makes a good sample for Copper in your collection of samples for the Periodic Table of the Elements, especially if you sand off the insulation.
