A copper wire with a square cross-section (side length 5.00 µm) is next to an iron wire with a rightward current of 3.00 A. The two wires are parallel over a region of 20.0 cm, where they are 1.60 cm apart. The iron wire produces a magnetic field on the copper wire. The copper wire is connected to a 5.00 V power source, with current directed rightward.
Data of copper: resistivity = 1.68 x 10-8 Ohm m; free electron number density = 8.50 x 1028/m3
