Here’s a quick build to show off fundamentals of electric current to new makers — or a cool party trick that might earn you a buck. [Jay] from the [Plasma Channel] shows off how you can make a simple motor with only three pieces of enameled wire in under five minutes.
Start with a roll of 26-guage — or thicker — magnet wire, and a pair of scissors or knife. For the base, wrap fifteen to twenty turns of wire around any spherical object about one and a half inches in diameter, leaving a few inches extra on both ends. Wrap those ends around your coil a few tines to secure it and straighten out the excess length — one will act as a support and the other will connect to your power source. Another piece of wire — similarly wrapped around the base coil — acts as the other support and the other terminal. Scrape off the wire coating from one side on both support wires and curl them into small loops. Halfway done!
