Step 1: Materials
-enameled copper wire
-magnet (strong, preferably a speaker magnet)
-circular shape (slightly larger than the magnet, used to coil copper wire)
-stereo wire (opt, could connect copper wire into stereo itself)
Step 2: Step 1
Note: choose a circular object that is slightly larger than the magnet to wrap the coil around because the closer the wire is to the magnet, the stronger the sound produced.
Step 3: Step 2
Step 5: Step 4
Note: Make sure the copper has contact with the stereo/stereo wire, not just the enamel.
