The generator experiment was a very interesting one and what would ultimately become our groups end of the year project. The principle behind this experiment was to generate voltage using a flashlight equipped with a magnet and a coil. The coil was located on the inside of the flashlight. Also within the flashlight was a magnet that could freely pass through the coil upon shaking. Instead of using the electricity generated to power the flashlight, it was read in volts using the NXT device. It’s important to understand that magnets generate a field around themselves which in turn allows them to produce electricity, by changing this magnetic field. The copper coil is used to create this change in field. It’s important however that this change takes place on the inside of the coil. Based on our end of the year experiment, our group found that a magnet on the outside produced little voltage compared to the magnet on the inside of the coil. I hypothesis that the change in magnetic field is not as great when the magnet is used on the outside. In this experiment we tested the variation of speeds at which the magnet passed through the coil by physically shaking the flashlight either slower or faster. The faster the flashlight was shaken, the greater the voltages were, because of Faraday’s law. Faraday’s law shows that the speed at which the magnetic field changes affects the voltages produced. When the magnetic field changes faster or more times consecutively, more electricity is created.
