Each of two parallel horizontal wires, running east-west, are seperated by 0.89 m, has a current of 4.8 A. Wire 1 lies North of Wire 2. Calculate the magnitude and direction of the magnetic field midway between the two wires if: a) The current is directed east in Wire 1 and west in Wire 2. (b) The current is directed east in both wires. Be sure to clearly explain your results. HINTS: (1) Magnetic field strength is a vector, so can be added/subtracted based on direction. (2) Consider the left hand rule for a straight wire to determine direction.
