Two wires, parallel to a $\backslash ($ z $\backslash )$ axis and a distance $6\mathrm{.}44$ m apart, carry equal currents $3\mathrm{.}58$ A in opposite directions, as shown in the figure. A circular cylinder of radius $1\mathrm{.}61$ m and length $6\mathrm{.}09$ m has its axis on the $\backslash ($ z $\backslash )$ axis, midway between the wires. Use Gauss' law for magnetism to find the net outward magnetic flux through the half of the cylindrical surface above the $\backslash ($ x $\backslash )$ axis. $($Hint: Find the flux through the portion of the $\backslash ($ x z $\backslash )$ plane that lies within the cylinder.$)$
