Transcript The Shocker

By: Jordan Clark, Jordan Hadden, Stephen Catignani
Summary of Design
At first we were going to spin the
magnets inside of a toilet paper role with
the copper wire wrapped around the
outside of the cardboard.
 This proved to be 100% inefficient, and
our makeshift generator was
embarrassed on the day it was tested a
week and a half ago.

Summary Again
Then we decided to wrap the copper
wire around a new structure, leaving
most of the wire completely open to the
spinning magnet.
 We also used some wood in order to
raise the windmill high enough to where
the maximum amount of wind is caught
from the fan.

Electrical and Mechanical

Electrical
 When the magnets
are turning it
conducts electricity
do to the magnetic
field created by the
magnets and the
wrapped copper wire.
 This then is able to
light the light bulb.
(Hopefully)

Mechanical
 The fan turns our
“windmill” causing the
magnets to then turn
simultaneously due to
the oily bearings.
Efficiency of the Shocker

Theoretical Yield : P = W / t; W = KE; v = L / t;
m(air) = ρAL; A = πr2
 KE = .5mv2 = .5ρALv2;
 P(air) = KE / t = (.5ρALv2) / t = .5ρA(L / t)v2
 P(air) = .5ρAv3
 P(air) = .5(1.201)(π(.0889 m)2)(9.4 m/s)3 = 12.38W

Produced Voltage: Volts = P / C = Watts / Amps

Watts = Amps(Volts) = 7mA(.4V) = 2.8mW = .0028W

Percent Yield : (.0028 / 12.38) * 100 < 1% 
Design Costs and Construction Issues

Costs
 Wood & Nails- $10.00
 Magnets- $6.50
 Copper Wires- $7.20
 Fan Blade & Bearings- $0.00
 Finding the only
Radioshack© that still has
magnetic wire in stock- Arm,
Leg, First-born, Full-tank of
Gas

Issues
 At first we though
about spinning the
magnet inside of a
toilet paper roll, which
proved to be
unsuccessful
 Then the open wire
was able to produce
some voltage…
hopefully enough
Conclusions

In the end, we learned how electricity
can be produced with only magnets and
copper wire and that a simple generator
really isn’t that hard to build.

But it will take a lot of wire.
