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

The figure below is a cross-sectional view of a coaxial cable. The center conductor is surrounded by a rubber layer, an outer conductor, and another rubber layer. In a particular application, the current in the inner conductor is I1 = 1.14 A out of the page and the current in the outer conductor is I2 = 2.90 A into the page. Assuming the distance d = 1.00 mm, answer the following.(a) Determine the magnitude and direction of the magnetic field at point a.find magnitude ut and direction(b) Determine the magnitude and direction of the magnetic field at point b.find magnitude ut and direction

Your employer asks you to build a 17-cm-long solenoid with an interior field of 4.7 mT. The specifications call for a single layer of wire, wound with the coils as close together as possible. You have two spools of wire available. Wire with a # 18 gauge has a diameter of 1.02 mm and has a maximum current rating of 6 A. Wire with a # 26 gauge is 0.41 mm in diameter and can carry up to 1 A. Part A Which wire should you use? #26 # 18 Submit Part B I = What current will you need? Express your answer to two significant figures and include the appropriate units.
