48. A wire frame is perpendicular to the magnetic field, the induction of which varies as: B = B0 (1 + e-kt), where B0 = 0,5 T, k = 1 s-1. The frame is made of aluminum wire having a cross section S = 1mm2. Determine the value of the emf induced in the frame having a square shape with a side of a = 20 cm, at time t = 2,3 s.
