Lab Report 9 1 Section 09: Electromagnetic Induction Sydney Marquez University of Texas at El PasoLab Report 9 2 Introduction In this lab, we will use Faraday’s Law of induction to explore how the electromotive force (emf) is generated when a coil moves through a magnetic gap (Pivot 09). Faradays Law states that the induced voltage in a loop of wire caused by a changing magnetic field is expressed as where The flux density B is not changing so ε =dtdΦA, magnetic flux. Φ = B = Φ dA.d = B Materials and Setup ● Pivot Interactions ● Magnet ● Glider ● Coil ● Wires ● Scale ● Conductor ● Ruler To set up this experiment a glider was along a ruler, to pass through a magnetic gap. For the second part of the experiment 2 magnets were placed on a scale and a copper wire was placed through the gap of the two magnets. Wires were attached to the copper wire and to a current device. Procedure Once our experiment was set up, the first part of our experiment was started. . Trial 3 was selected and the voltage in mV, time, and distance in m was recorded for the duration of 5.6 seconds. This data was then graphed and analyzed. The second experiment was set up and theLab Report 9 3 current was increased and as the voltage increased the weight of the magnet was recorded. Using the weight we found the Lorentz force in Newton by dividing the mass in kg by 9.81m/s^2. Data and Data analysis Figure 1 Electromagnetic Induction Interactive Figure 2 Field Using Lorentz ForceLab Report 9 4 Figure 1 shows the glider velocity vs emf graph of the first experiment. The slope of this graph is 2.946m/s/V. The velocity was found by dividing the change in distance over the change in time for each point. Figure 2 shows the current vs lorentz force with experiment 2 where the magnets were placed on a scale. The slope of this graph was 23.12amps/N. Conclusion In both parts of the experiment the data was linear. Meaning both variables measured had a direction relationship to eachother. Using Faradays law and the data provided by the graphs we are able to solve for different variables such as magnetic flux density, B. Using the formula E=NBlV, we plugged our values in to solve for B. For experiment 1 our magnetic flux density was 0.472T and for the second part our magnetic density flux was 0.289T. Personal Learning Experience From this lab, I was able to understand and see how the results of the experiment can vary depending on the set up you use! I really enjoyed being able to gain an understanding on multiple ways to approach an answer and using a different set up to get those solutions.Lab Report 9 5 References Interactives, P., & Marquez, S.
