→Rolling Coil: added link to your electricity literature review
# Attach one large washer to a 4 inch screws.
# Attach the 10 inch piece of ribbon with a small piece of electrical tape and wrap it all of the way around the screw in the space between the washers. This piece of ribbon should be a big enough that its diameter is bigger than the size of the magnets you're going to use to produce electricity.
# Slip the other 2.5 inch washer onto the screw leaving about 1.5 inches of space between the two washers. (You can adjust the size of the space between them based on how big you want to roll your coil.)
# Carefully take the end of the copper coil and wrap it around the end of the screw that is on the outside of the 2.5 inch washer. Make sure it's firmly wrapped so that its stays in place.
