A square loop of side 7 cm is placed with the nearest side 2 cm from a long wire carrying a current that varies with time at a constaent rate of 9 A/s. (Assume the loop and the wire lie in the same plane. Further assume I- 0at t 0. Enter the magnitudes.) (a) Use Ampère's law and find the magnetic feld from the current in the wire as a function of time and dstance from the wire. (Use the folowing as necessary: j is in meters and t is in seconds. Do not include units in your answer) , and t. Assume 8 is in teslas, r Br, t) (b) Determine the magnetic flux through the loop. (Use the following as necessary: and t. Assume is in T m and t is in seconds. Do not include units in your answer) (c) If the loop has a resistance of 3 0, how much induced current flows in the loop (in nA)) nA
