Results and Conclusions: For this lab, our purpose was to study the effects of magnetic fields in motion and how electromagnetic induction. By using three different types of magnets (bar magnet, electromagnet, and electromagnet w/ iron core), we can explore Faraday’s law and Lenz’s law to better understand the complexities of magnetic fields. In part A, using the bar magnet, we pushed it in and out of the solenoid coil to measure the current which was the change in flux. Jay has indicated in the Data and Calculations more detailed information about this including sketches of the magnets. Using the following equations for magnetic flux and calculating the induced emf we learned more about how to use Faraday’s law: ε = t ∆Φ Ф = NBA cosθ Obviously we can say that a change in the velocity of the bar magnet changed the magnetic field and flux. Because of this change in flux there is a potential difference in velocity. The galvanometer measures the induced current regardless of the direction the
