As seen in pictures 1,2, and 3, the first three runs are relatively the same: all three are basically the same curve, with the same amplitude and very similar distribution of data points. The only real difference is the positions of the peaks on the graph. While the center peak was very close to zero, where is was supposed to be, the east and west graphs were pushed out towards the far left of the graph into the negative zero of about 120 cm. We ran multiple runs of each but couldn't seem to find the reason as to why this happened. From this data, we can tell that the magnetic field is moving upwards, towards the observer, in the coil, which means that the current in the coil will be rotation counter clock- wise. In observing the final run, the east reversed shown in picture 4, we known that the reason why the graph looks the way it does is because we switched the cords before running this part of the experiment. By switching the cords, the magnetic field was flipped, giving us a downwards field was a clock- wise current. As seen in data table, our bound values for the magnetic field strength was larger than our experimentally gathered data, but not to far from our values. Experimentally, our average magnetic field strength was 18.73 mT; equation I gave us a value of 21.92 while equation 2 gave us a value of 26.3 mT. By comparing these three values, our solenoid is much more like a short solenoid than a large solenoid
