A direct current I=10A flows in a long straight round conductor. Find the magnetic flux through a half of the wire's cross-section per one meter of its length.

A direct current I flows in a long straight conductor whose cross section has the form of a thin halr-ring of radius R. The same current flows in the opposite direction along a thin conductor located on the axis of the first conductor. Find the magnetic induction froce between the given conductors reduced to a unit of their length.
