You will use this to calculate the induced potential difference around the coil. Read Sternheim & Kane Chapter 20, sections 1. E QUIPMENT You have a coil of 200 turns of wire, a magnet, meterstick, cart, and track. The track is raised at an incline using wooden blocks. You also have voltage probe with software called VoltageTimeLAB. If you need assistance, send an email to [email protected] . Include the room number and brief description of the problem. W ARM UP 1. Draw a picture of the situation. Label important distances and kinematic quantities. Decide on an appropriate coordinate system and add it to your picture. 2. Use Faraday’s Law to relate change of magnetic flux to the magnitude of the induced potential difference in the coil. 3. Draw a magnetic field map of a bar magnet. Draw the coil of wire on the magnetic field map. As the bar magnet passes through the coil, when is the flux change the strongest? What is the relationship between the velocity of the bar magnet and the change of the magnetic flux through the coil? This tells you, qualitatively how the flux changes with time. 4. Look at the time rate change of the magnetic flux. How is it related to the velocity of the cart? It is important to note whether or not the quantities of interest vary with time or with the cross-sectional area of the coil. 5. What physics principles can you use to determine the velocity of the magnet as it passes through the coil to the starting position of the cart? Table Magnet Cart Coil Track Table 163
