So Whats the Deal?

Magnets, containing a magnetic field measured by “flux” (Φ ) or quantity of magnetism, spin inside the generator casing.

This spinning of the magnetic field causes a “change in flux” which produces an electrical field.

This phenomenon is known as Electromagnetic Induction.

Wrapping copper wire around the generator casing allows for the transmission of the electromagnetic field.

Design

Wooden Base, with braces holding upright Used 30 gauge wire, cardboard magnet housing Generator is a compact design, simple but

efficient Bulb mounted on top of wooden base

Equations

1.15 volts 29 miliamps

P = 0.5 x ρ x A x V3 P = (.5)(1.225)(.0153)(6.7)^3 = 2.82 Watts Pelectrical= I x V = .029 amp x 1.15 volts = .03335 watts Efficiency = Useful power/ Total Power = 1.18%

Conclusion

All in all it cost us $20.00. Simple design but effective.

Produced 1.2 volts 1.18% efficient Trial and error = best friend Took a total of 14 hours
