A square wire frame with side
a and a straight conductor carrying a constant current
I are located in the same plane (Fig.).
The inductance and the resistance of the frame are equal to
L and
R respectively. The frame was turned through
180∘ about the axis
OO′ separated from the current-carrying conductor by a distance
b. Find the electric charge having flown through the frame.
