2) What is the magnetic field (magnitude in [T] and direction) at the center of the circular region. You can assume that the two long straight wires are effectively infinite and located 8 [cm] apart, with a current of 20 [A] flowing as indicated by the arrows (this is really a very long wire out-and-back so those two wires are carrying the same current). Hint: for goodness sake don't try to set up an integral here, but try to solve this from the standpoint of different parts contributing different magnetic fields. 90°
