Power Project Lab Report

October 15, 2008


For this project, our class had to research and build generators that we think will be the best to light an LED, light a light bulb, run a motor, and heat a hot plate. Our group consists of Kaitlyn Markola and Liz Saint Germain. We chose Kaitlyn's crank generator over Liz's electric generator.


For this trimester, our class has been working on generators. We will then use them to heat a bowl of water on a hotplate for 10 minutes. We cannot use any thing over $2 and it has to be raw materials that can be found in the classroom. In our groups we had to choose which generator we thought would be the best for what were working on. Our group consists of Kaitlyn Markola and Liz Saint Germain. We chose Kaitlyn's crank generator to heat the hot plate.

We found the generator on, and there is a video on how to make it, along with steps. When the magnets spin they make electricity in the wires which make the hot plate warm. A magnet has two sides on it; the north side and the south side. If you put two north sides together or two south sides together then they move further away from each other. But if you put a north side and a south side together then they attract, thus creating a magnetic pull, causing electricity.

The way this generator works is the nail is working as a rod to spin the magnets. The magnets push away from it causing them to spin. When the magnet spins, the electricity that is caused by magnets goes through the wire and to the hot plate and heats up the water.

This is a picture of our generator.

Materials and Methods


· Cardboard

· A Nail

· Magnetic Wire

· 4 1X2X3 magnets


1. Cut the cardboard.
2. Fold cardboard to make a box.
3. Wrap the magnetic wire around the cardboard 300-200 times.
4. Put a nail in the exact center of the box.
5. Put 4 magnets into the box around the nail.
6. Attach card board to nail to make it spin.
7. connect wire to LED bulb and spin nail.

Our genorator didn't light the LED bulb. When we tested our genorator on the multimeter it said that it was 0.04 volts. We decided that we have to put more wire on it (we didn't put enough on the first time). We're also going to make the box slightly larger. The magnets kept getting caught on the cardboard/ tape when we were spinning it because they were too close to the magnet.
