A wide, long, insulating belt has a uniform positive charge per unit area o on its upper surface. Rollers at each end move the belt to the right at a constant speed v.

Calculate the magnitude of the magnetic feld produced by the moving belt at a point just above its surface. ( Hint: At points
Calculate the magnitude of the magnetic feld produced by the moving belt at a point just above its surface. ( Hint: At points near the surface and far from its edges or ends, the moving belt can be considered to be an infinite current sheet.) Express your answer in terms of the variables \( v, \sigma \), and magnetic constant \( \mu_{0} \).
