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

Power & EffeciencyVfan = 20 mph, 8.9408 m/sA = .05067 m V = 5.2987 Volts
PPotential = pAV3PPotential = (1.204)(.05067)(8.94083) = 22.1813 Watts
Effeciency = (Actual)/(Potential) x 100 = (.56/22.1813) x 100 = 2.525 % Pactual = I x V Pactual = .56 Watts
ConclusionGenerators are not as hard as they lookGetting the right materials is keyUsing a magnetic field to generate electricity is simple and fairly easy.
