4. Consider the situation below. A long straight wire carries current I moving upward. At the same time a conductive square loop with resistance R and side-length x is placed next to the wire. a. If the loop is moved at constant speed v downward, in which direction does the current flow? Explain your answer in complete sentences. b. If the loop is moved at a constant speed v to the right, in which direction does the current flow? Explain your answer in complete sentences. I X
