Question

Consider a thin, infinitely long conducting ribbon that carries a uniform current density j (current per unit area). The width of the ribbon is w and its thickness s is extremely small (s≪w). P is a point in the plane of the ribbon, at a large distance (x≫s) from the ribbon edge.

What is the magnitude of the magnetic field B (in T) at point P for the following values of w , j, s and x?
w= 5 cm; s= 0.1 cm; j=1A/m2 and x= 21 cm
