Sources of Magnetic Fields

July 23, 2012 - 7th Meeting of Physics 102.1 Lab

Today, we started to engage in the world of magnets, primarily the sources of magnetic fields. We examined the features of a bar magnet, although our materials are a bit off when it comes to accuracy. After that, I sprayed some iron fillings on a piece of paper and investigated the way the bar magnet interact with it. The results are great, yielding the structure if its magnetic field. 

However, the observation of Oersted's Experiment and the solenoid coil is the hardest thing we did that day. Our power supply was defective, smoking out when shorted with a wire. Although these things were cumbersome when it comes to data gathering, we never stopped the activity. Nelson, was a bit reluctant about the whole experiment, considering the absence of our third member. Nevertheless, the experiments were finished, and we get to learn new things in our laboratory.
