30-32 gauge wire
Neodymium magnets (at least 6)
Hot Glue Gun
2 Alligator clips
Piece of cardboard that is bigger than the styrofoam plate

On the back of the plate, glue the piece of paper to the center using hot glue gun.
Step 5: Begin Wrapping Wire Around Paper
Using 30-32 gauge wire, wrap it around the piece of paper glued to the plate. Continue wrapping it until the majority of the piece of rolled paper is covered in wire. Once wrapped, cut the wire and secure it with piece of tape.
It helps to start wrapping the wire from the bottom and go up.
Step 6: Sand Ends of Wire
