I connected the whole thing up, brought my ceramic magnets within close proximity to the coil.
Before I brought the magnet into vecinity I watched with horror as the 22 AWG wire's insulation melted back and I saw the solid wire red-hot...actually orange. Smoke followed this.
At any rate it worked!
How did I make it?
Materials:
- Magnet wire - it's copper with a transparent coating
- Magnets - I used 3 ceramic magnets stacked together
- Battery - 12 v - probably more than I needed, but hey, it's what I had available
- 2 Paper Clips
- Sharp knife (used to scrape some of the transparent coating from the magnet wire
Steps:
- Take ~3 ft of magnet wire and wrap it around something like a D-battery...I used a wooden cylinder-shaped block from the toy-box. Leave about 1.5 inches on each end.
- Scrape the transparent coating off one half of the tails of the magnet wire.
- Make a stand out of the paper clips. One for the left side and one for the right side. They should NOT be touching.
- Place the loop (the armature on the stand
- Place the magnets near the wire loop
- Connect power to both paper clip stands - negative on one side, positive on the other
- If the motor (armature) does not start to rotate then tap it a bit so the scraped sections of the armature can briefly touch the energized paper clip stands
