Figure shows a cross-section of a long ribbon of width omega that is carrying a uniformly distributed total current i into the page. Calculate the magnitude and direction of the magnetic field B at a point P in the plane of the ribbon at a distance d from its edge.

A thin sheet of width 2a is placed in the x-y plane between the lines x=-a and x=a . The sheet is very long in the -y and +y directions. It carries a current l towards the +y direction. This current is uniformly distributed over the width of the sheet. The magnitude of magnetic fiedl at the point P(2a,0) due to the sheet is (1/n)((mu_(0)I)/(pia))log_(e)3 . Here the value of n is ______________.
