Description
• Summary: Our generator was made by gluing two
pieces of plywood to each end of four wooden dowels.
We then attached four magnets onto a brass rod and
ran it through a hole we had drilled out in the box.
Finally, we put the fan blades on, added a coke bottle
filled with water to add weight, and mounted the
entire thing on a ply wood base.
Materials
 Materials list:
- Enamel coated wire ($21.00)
- 4 magnets (2 x $3.00)
- Fan blade ( cost of fan $7.00)
- Brass rod ($1.00)
- plywood ($2.00)
- 1 wood dowel ($1.00)
• Total Cost: $38.00
Calculations
 Equations:
KE = ½ mv^2
P = 1/2ρ(air)Av^3 (theoretical)
Efficiency = P (actual)/ P (theoretical)
• Readings:
- Volts: 2.5 volts
- (theoretical ) Power: 104 watts
- (actual) Power: 0.213 watts
- efficiency: 0.2%
Problems
 Problems Encountered:
- Finding the proper wire and magnets to use.
- Finding which fan blade would work best.
- Not producing enough volts.
- Originally had an unstable generator.
