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)

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.

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

Power & Effeciency V fan = 20 mph, m/s A = m V = Volts P Potential = ½ pAV 3 P Potential = ½ (1.204)(.05067)( ) = Watts Effeciency = (Actual)/(Potential) x 100 = (.56/ ) x 100 = % P actual = I x V P actual =.56 Watts

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.
