Simple Electric Motor Masco G39

Introduction: Simple Electric Motor Masco G39


  • D battery
  • 2 paperclips
  • Copper wire
  • elastic
  • Sandpaper
  • Scissors

Step 1: Instructions

  1. Gather your supplies
  2. Cut approximately 25 inches of copper wire with scissors
  3. Coil wire around battery leaving about 2 inches of uncoiled wire on either end (video)
  4. Wrap ends of wire around edges of coil to secure in place
  5. On one wire end, sandpaper enamel off all the way around, but leave some un-sandpapered wire before coil
  6. On the other wire end, sandpaper enamel off on only one side of the wire. Half should still have enamel while the other doesn't. (see fig.1)
  7. Bend one end of paperclip, into a hook shape (See picture 2)
  8. Using an elastic, connect the paperclips to the positive and negative end of the battery (See picture 3)
  9. Place a small magnet, on top of your batter, making sure it's lined up with your paperclips
  10. Finally, balance the coil within the hooks made in the paperclip, right above the magnet, should start spinning (as seen in video) once built. (see picture c for steps 9 and 10)

Step 2: Trouble Shooting

In the event that the coil doesn't spin with the magnet, it could be a result of too much excess wire on the ends of the coil. Try to trim any excess wire at each end of the coil. If you fix the coil, and the problem persists, try using a different battery or a stronger magnet.

    Why are you going on all of these same instructables giving praise? If you examine the date of joining, all of these "Simple Electric Motor Masco" type instructables are close together. It appears that either a mass group of individuals decided to post nearly the same ible within a short time period, or, someone is account spamming.

    We all made these for our Engineering final, and are having the middle-school students try and construct them.
