1. The loop of wire to the right carries a current in the counterclockwise direction. Draw in the direction of the magnetic field that it creates inside the loop. 2. A second loop creates a magnetic field pointed into the board as shown to the right. Which direction must that loop be carrying current to produce that magnetic field? 3. Faraday's law can be written E = - dem dt where the magnetic flux is Pm = B . A = BA cos 0 Define each of the symbols in Faraday's law and explain how Lenz's law fits into Faraday's law. 4. Acceleration is defined as the change in velocity with time, much like the induced voltage in Faraday's law. What direction is the acceleration in the following cases: a. Traveling to the right and speeding up b. Traveling to the right and slowing down c. Traveling to the left and speeding up d. Traveling to the left and slowing down 5. A circular wire loop is placed in an external magnetic field as shown. The magnetic field is directed into the page and the strength of the magnetic field is decreasing. For each of the following, choose the proper choices that describe the physical situation. a. There is (more/less/unchanging) magnetic flux directed (into/out of) the page. X b. To oppose this change in flux, the induced magnetic field is directed (into/out of) the page. X c. The induced current in the wire loop that creates this induced magnetic field is directed (clockwise/counterclockwise).Open the interactive activity found here: https://phet.colorado.edu/en/simulation/faradays-law Begin by checking the boxes for "Voltmeter" and "Field Lines". You are then able to click the magnet and drag it around to see what effect you have on the coil of wire and lightbulb. Questions: 6. If current were running in the coil in the positive direction, that is toward the positive terminal on the voltmeter (from right to left on the coil), which direction would the resulting magnetic field be? (Hint: Use the right-hand-rule to grab the wire around the edge of the coil, such that your thumb goes the way of the current - which way do your fingers go?) 7. The amount of magnetic flux can be visualized by the number of field lines going through the coil of wire from right to left. Field lines which go through the coil along the direction corresponding to the field made by a positive current is defined as positive flux. As you move the magnet from right to left, how much magnetic flux (little/lot, positiveegative) is there through the coil when the magnet is.. a. far on the right? b. close on the right? c. in the middle of the coil? d. close on the left? e. far away on the left? 8. Move the magnet through the coil at a constant rate from right to left. At what points does the lightbulb light up the most? At what points does it not seem to light up at all? 9. If the magnetic flux is made to increase then what is the sign of the induced voltage? Use Lenz's Law to explain this
