do =B-dA &=-5 dt Please circle the correct answer for questions 1-2 and 4, showing your work for question 3. 1. In the figure shown at the right, a steady current I flows through the wire. In which direction does the induced current flow R around the rectangular loop containing the resistor? A. clockwise B. counterclockwise C. no induced current 2. In the figure for question 1, if the current I flowing through the wire is increasing, in which direction does the induced current flow around the rectangular loop containing the resistor? A. clockwise B. counterclockwise C. no induced current 3. Consider a circular loop of wire with radius a = 0.500 m in a uniform magnetic field, pointing into the page as shown in the figure. The loop has resistance 15 02, and the initial field strength is 0.45 T. If the strength of the field is steadily decreased to 0.10 T in 3.0 seconds, what is the induced current in the loop while the field is changing? 0 e Ⓡ 0 0 0 0 0 0 0 0 0 0 Φ Φ 9 40 4/4 Ⓡ • • • +/+ + + Ⓡ B 99 B B B
In the figure at the right, a steady current I flows in a long straight wire. If the rectangular loop is pulled away from the wire (upward in the figure), in which direction will the induced current flow around the loop while it is moving? Write your answer for the direction (CW or CCW) in the box below, and explain your reasoning in detail, using complete sentences. I
