Consider a straight piece of copper wire of length 8 m and diameter 8 mm that carries a current I = 4.5 A. There is a magnetic field of magnitude B directed perpendicular to the wire, and the magnetic force on the wire is just strong enough to “levitate” the wire (i.e., the magnetic force on the wire is equal to its weight). Find B. Hint: The density of copper is 9000 kg/m3 .

4.A coaxial cable has an inner core of copper wire with a 3 mm diameter with a current density of 1.768E4 A/m2. The image shows a cross-sectional area of the wire. The current in the core is flowing out of the page. The core is surrounded by a thin sheath of insulating material, 1mm thick. Surrounding this is a thin cylindrical shell of copper wire 1mm thick, that carries the returning current back into the page. The copper shell is...
