So What’s 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.

The Light In The Sky’s
Design

Wooden Base, with wooden braces holding
upright

Used 32 gauge wire, wooden magnet housing

Added cotton balls to give sky effect.

Bulb mounted on top of wooden base
Equations
P = 0.5 x ρ(density) x A(area) x V3(voltage)
Pelectrical= I(current) x V(voltage)
Efficiency = Useful power/ Total Power
Conclusion



All in all it cost us $30.00
Could not get it to put out a current after several
attempts and different wire/magnet
combinations
Took a total of 12 hours
