Three long parallel wires each carry 2.0-a currents in the same direction. the wires are oriented vertically, and they pass through three of the corners of a horizontal square of side 4.0 cm. what is the magnitude of the magnetic field at the fourth (unoccupied) corner of the square due to these wires? (μ0 = × 10-7 t · m/a)
