o On the slide, there is a xy-looking plot where the y-axis indicates an ammeter reading of 0. You are tasked with placing the vectors for each case on this plot. The vectors should have all the same length and start from the origin. The magnitude is determined by the angle the vector makes with the y- axis. The larger the angle, the larger the induced current. Before you plot, we rst need to calculate the magnitude of the current AND determine its direction (based on if the EMF is positive or negative). 0 Now that you know the end goal, it's time to collect data for each case! Please watch the data collection video for A2. 0 Dr. Woods indicates the maximum strength of B for each case. Yourjob is to record how much time it takes to either go from maximum eld to no eld or vice versus (depending on the case since its the same for all cases) and record the time it takes with a stopwatch. o The change in magnetic ux, A'i', will just be the change in the magnetic eld (we will ignore area). The change in time, At, will be the time interval you recorded with your stopwatch. Do not forget to multiply by the negative sign! I suggest timing each case 3 different times and taking an average to get the most accurate result. - NOTE: The direction of the original magnetic eld matters. Recall the formula for magnetic ux has an angle dependence with the normal vector of the cross-sectional area. In this lab, the normal vector is pointing towards us ("out of the page"). Thus, in this lab, 6 will either be 0 or 180 degrees depending on the scenario. - If you have a negative EMF, the angle with the y-axis should be on the left. If you have a positive EMF value, the angle with the y-axis should be on the right. 0 Record your EMF value, 6, for each case on the PowerPoint slide. 0 The next step is to determine the induced current. Recall Ohms Law is V = IR. Dr. Woods gives the resistance as 2 ohms which is the same for all cases. Thus, you have your induced voltage and you have the resistance, so you can nd the induced current. Whether the current is positive or negative indicates the direction it's owing around the coil. 0 Record your current values for each case on the PowerPoint slide. 0 Next, you have to do is plot the current vectors! Again, the larger the angle, the larger the EM F/induced current. The length of the vectors should remain the same, and they should all start from the origin. 0 The last thing I want you to do is justify your results on slide 3. This means quantitatively showing any calculations you did and qualitatively explaining your work, any assumptions you made, and ultimately why you made your nal choice to plot your vectors the way you did.
