My Generator and how it works
September 30th, 2008

For this trimester, our class has to individually construct and show a generator that we think will heat a hotplate for 10 minutes. After we construct our projects, we will meet and discuss our contraptions with our groups and find out which one is the best. For this project, we could only use parts that were in the classroom or parts that were under $2. All of our materials must be raw materials and if anything came from a book or the internet, we had to site our source.
A generator works on a magnetic field making a lot of electricity, an example would be a coil of wire. “Important points to note are that the voltage increases as the number of turns of wire on the coil, the size of the coil and the strength of the magnetic field increases” (from the website).
For my project, I chose an electric generator I found on http://www.creative-science.org.uk/gen1.html. How ever, instead of using a drill, like on the website, I will be using a Y shaped piece of wood, and it will have magnets and elastics on it. When I shake the elastics, the magnets will go back and forth so I don’t hurt my hand doing it myself. I chose this generator because I thought it would be the best suitable for the topic. In order to heat the hot plate, and not just and LED, I was going to put a thicker wire on with more coils. “Thick wire means there will be less power loss, but the down side is that the coil will get very large when a great number of turns are needed.” The nail is also important in the generator because it focuses the magnetic field. The type of wire in the coil is important too. The coil is wound around the nail because it puts in more magnetic alteration into the area of the coil which boosts the success of the generator.
