Two long, straight wires are set parallel to each other, a distance d = 10.0 cm apart. The two wires have currents flowing through them in the same direction; the left wire has a current if I1 = 1.50 A, and the right wire has a current of I2 = 4.50 Aa) Find the magnetic field (both magnitude and direction) exactly half-way between the two wires.b) Find the location between the two wires where the magnetic field will be zero. Give your answer as a distance from the left wire.
