Experiment to generate electricity
using the parallel small lamp stand
Figure 1 shows the parallel small lamp stand where four small lamps are attached
in parallel. While one person turns the handle of the Genecon and the other
person turns on the small lamps one by one, changes in the resistance of the
handle can be felt.
Figure 2 shows two Genecon units connected to the above parallel small lamp
stand.
Two persons each hold one Genecon. When one person turns the handle of one
Genecon at a constant speed, the handle of the Genecon held by the other
person will start to rotate at almost the same speed.
Then, as the person who holds only one Genecon turns on the small lamps one
by one, the rotating speed of the handle slows gradually. This experiment is
useful in understanding “generation and work” and “the loss of energy conver
-
sion”.
Let’s conduct an experiment using an electric magnet with an iron coil
1. Wind the conducting wire around the small plastic bobbin to make a coil for
the electric magnet.
2. Connect the Genecon to the terminal of the bobbin and turn the handle.
3. When you bring Gem clips, iron powder, or B10-3720 Mag chips close to one
end of the iron coil, the objects will be drawn to the tip of the iron coil.

Experiment using large-capacity condenser
Charge the condenser using the Genecon V3. Then, when releasing the handle,
the handle turns by itself and grinds to a halt after discharge. Also, when the
Genecon is removed after the charge and a small lamp is connected, the lamp will
glow and then dim after discharge. These experiments are considered energy
conversion. The use of the condenser base for the Genecon V3 allows the more
accurate experiment to be conducted.
Charge the 1F condenser.
Remove Genecon V3 from the charged condenser
and connect a small lamp.

Experiment of electric magnet
Experiment of energy conversion
Let’s conduct an experiment as a pair after combining two Genecon units.
The Genecon whose handle is turned will be the generator and the Genecon
that rotates will be the motor.
Wind a nichrome wire (0.2 mm) 10-15 times around the heat sensing part of a thermom
-
eter (100°C) and connect both ends of the nichrome wire to the lead wire of the
Genecon and then turn the handle of the Genecon.
Attach the Genecon to the resistance with a liquid crystal thermometer as shown in the
figure and turn the handle to see the scale of the liquid crystal thermometer change.
