  1. Perry’s Windmill -Alyssa Schroder- -Christina Fraser- -Tiffany Blevins- -Zack Henley-

  2. Materials • Wood ($11.19) Total = $39.12 • Wire ($6.59) • Magnets ($8.00) • Paint ($4.00) • Glue ($1.99) • Screws ($.40) • Metal bar ($2.97) • Epoxy ($3.98)

  3. Design • Generator We connected two magnets to a rod which rested in a wooden box. Approximately 600 feet of wire are wrapped around the box to collect the magnetic field. • Windmill We connected five wooden propeller blades to the rod connected to the magnets. Which spin the magnets creating the magnetic field.

  5. Construction Issues • How to spin the magnets? • What size magnets? • Which way to wrap the wire? • What materials to use? • Size of propeller blades?

  6. Power & Effeciency • Vfan = 20 mph, 8.9408 m/s • A = .05067 m • V = 5.2987 Volts • PPotential = ½ pAV3 • PPotential = ½ (1.204)(.05067)(8.94083) = 22.1813 Watts • Pactual = I x V • Pactual = .56 Watts • Effeciency = (Actual)/(Potential) x 100 = (.56/22.1813) x 100 • = 2.525 %

  7. Conclusion • Generators are not as hard as they look • Getting the right materials is key • Using a magnetic field to generate electricity is simple and fairly easy.
