In this experiment my partners and I explored Faraday’s Law.  This law states that changing magnetic fluxes through coiled wires generates electricity.  In order to change change the magnetic flux, a magnet has to pass through the coiled wire.  This law also states the greater the change in magnetic flux, the greater the current and voltage that is generated.

During this trial we used a tube attached to a reader that was hooked up to the computer.  The tube, shaped like a small flashlight, contained coiled wire and a magnet.  When you tilted the tube upright or downward, a magnet would fall through the coiled wire.  We connected the tube to a reader that was able to record the magnetic flux and electricity generated, but we had to count how many times we shook the tube manually.      

In this lab we shook a tube, which had a magnet in it that traveled back and forth through coiled wire, in five different trials to generate varying amounts of current and voltage.  In each trial we had a 30 second time frame to shake the tube.  In each trial we shook the tube more times.  After looking at all the data provided from the trials, we came to the conclusion that the more times we shook the tube, and the more times the magnet passed through the coiled wires, the more electricity we generated.
