Explanation Given Info: Charge per unit area of the belt is σ and the speed of the belt is v . Write the expression for the magnetic field of an infinite current sheet. B = μ 0 N I 2 L (I) B is the magnetic field μ 0 is the permeability of free space N is the number of turns L is the length I is the current The factor 2 in the denominator is due to contribution from the two sides of the sheet. The charge on the belt is, Q = σ L Δ x (II) Q is the charge Δ x is the length on the belt Write the expression for current. I = Q t (III) t is the time Use Equations (II) and (III) in (I)
