3 feet of 22-gauge solid core insulated wire |
|
2 disk magnets |
|
2 insulated test cables with a clip on each end |
|
1 plastic cup |
|
2 large rubber bands |
|
2 jumbo-size paper clips |
|
1 D-cell battery |
|
Wire strippers |
|
Waterproof marking pen |
|
|
|
|
|
|
Take the 3-foot piece of insulated wire.
Starting about 3 inches from the end of the wire, wrap it seven times
around the D-cell battery to form a coil. Wrap the ends of the wire a
couple of times around the coil to hold it together. |
|
|
|
|
Use the wire strippers to remove the insulation
from the two ends of the coil. |
|
|
|
|
Hold the coil vertically. Use the permanent
marker to paint the TOP HALF of one of the two end wires. Allow the ink to
dry for a few seconds, and apply a second coat. Allow several seconds again
for the ink to dry. |
|
|
|
|
Straighten the larger loops of the two paper
clips. |
|
|
|
|
Turn the cup upside down and place a magnet on
top in the center. Attach another magnet inside the cup, directly beneath
the original magnet. This will create a stronger magnetic field as well as
hold the top magnet in place. |
|
|
|
|
Put two large rubber bands around the base of
the cup. Insert the straightened
paper clips into the rubber bands, so they stand upright over the bottom of
the cup. |
|
|
|
|
Rest the ends of the coil in the cradles formed
by the paper clips. Adjust the height of the paper clips so that when the
coil spins, it just clears the magnets. Adjust the coil and the clips until
the coil stays balanced and centered while spinning freely on the clips. |
|
|
|
|
Attach one of the clip cables to each paper clip
just above the rubber bands. You may need to readjust the clips to make
sure the coil still spins freely. |
|
|
|
|
Hold the other ends of the clip leads against
the two poles of the D-cell battery and give the coil a gentle spin. The coil should continue to spin
rapidly. |

If that doesn’t work, well, what can I say? You
suck. Richard Dean Anderson laughs
at your stupidity. |
