The following instructable will show you how to easily construct a motor powered by a battery, magnet wire, a magnet, elastics,and paperclips.
Step 1: Step 1. Materials & Tools
First, you are going to need to gather
2 small or large paper clips
2 or 3 rubber band elastics
1 D battery
1 small magnet (about the size of a quarter)
A small four to six inch square of sandpaper
An arms length of 26 gauge magnet wire
A pair of wire cutters
Step 2: Step 2. Gathering Wire
First you are going to want to measure an arms length of 26 gage wire from shoulder to fingertips using the spool of magnet wire. Then you are going to take your pliers and cut the wire on the inside sharp edge of the pliers.
Step 3: Step 3. Coiling the Wire
Taking the arms length of wire you are going to start at the left or right end of the battery and coil the wire around the battery, with roughly two inches of wire sticking out on both sides. It is supposed to look like this.
Step 4: Step 4. Assembling the Coiled Wire
Remove the wire by pinching it and slowly sliding it off to the left left or right side. Pinch the coils when taking it off so it forms a ring. Taking the two inches of non coiled wire and wrap it around the ring three or four times on each side so that the extra wire of two or so inches lie directly horizontal from each other. The free now sticking out from each side should be 1 1/2 inches, if wires are uneven in length but them with pliers so they are even.
Step 5: Step 5. Stripping the Wire
Then after making sure the non coiled wire lies horizontally, strip the enamel entirely off of one end of the non coiled wire by rubbing it in an up and down motion with sandpaper and then with the opposite end of the non coiled wire, strip only half the enamel off. The ending result should look like this.
Step 6: Step 6. Putting the Elastics Around the Battery
Take one elastic and wrap it vertically around the battery one, and wrap it around once more so the rubber band is wrapped around it twice. Then repeat this action with another elastic so it will look like this.
Step 7: Step 7.
Take your two paperclips and undo them from there original form so they look like this.
Step 8: Step 8. Place the Paperclips.
The after wrapping elastics around battery insert paper clips on opposites sides of the battery under elastics so the are touching oppostie charged poles of the battery but not touching each other. Make sure that the curved parts of the paper clips are facing up and towards the same direction. Place paperclips under all elastic so that they will be sturdy.
Step 9: Step Nine
Then proceed to balance the straight horizontal wire on the two curvatures of the two paperclips, so that the ring of wire rests directly paralell to the battery.
Step 10: Step Ten
Place the magnet directly under the ringed coiled so that is directly below the ring, and place it on top of the battery and any elastic.
Step 11: Step 11
With completing all of these steps, your coiled wire ring should begin to spin in a circular motion.
Step 12: Trouble Shooting
If you see that your wire does not being to spin, if yu used small paper clips you could also try using bigger ones, and also adding another magnet if available. If neither of these work go back to the first beginning steps and make sure the enamel is stripped completely down on one side, and only half in length on the other. Make sure that the extra wire is directly horizontal from each other and the ring is as perfect and as even as a circle that you could possibly get. Make sure that the paperclips are facing the same way and the wire is placed evenly between them and the magnet is places directly underneath the ring, if this doesn't work shift the magnet to the other side of the battery.
