There are billions of people on this earth whose lives are entirely dependent on electricity and energy use. However, as many of our sources of coal and natural gas are becoming exponentially smaller we must examine how we generate our electricity more closely now than ever.
When a person thinks of calories they most likely think of food, but a calories is actually in fact a unit of energy. As you burn calories you are in fact burning stored energy in your body.
The experiment is centered around our body’s ability to produce energy using Faraday’s law. According to the law, changing magnetic fluxes through coiled wire generates electricity just a generator would. The greater the change in the magnetic flux the greater the voltage generated.
In a generator there is some sort of engine that powers a coil which rotates to interrupt the magnetic fields in order to create a current. (As seen below) However during our experiment we shook a tube that has a magnet within which travels back and forth through a coil of wires. The faster the tube is shaken or the higher energy that is used the higher the voltage.
When recording data our task was to correlate the number of shakes of the generator, in a thirty second time interval, with the voltages that the generator generates.
However, when conducting our actual experiment we ran into numerous amounts of problems. We switched out multiple batteries only to find that the program still couldn’t connect to the computer. Even when the computer said it was connected to the lego mindstorm device we were still unable to generate data.
Had it gone correctly we hope that the data would have correlated higher according to how hard the tube was shaken.
