The easy way: The side s is the perimeter divided by 4. The side at time zero is s(0) = 1 m. At one second, s(1 sec) = 0.99 m. Using , B(0 s) = (0.1 T) (1 m2) and B(1 s) = (0.1 T) (.992 m2) Emf = - = 2 mV. As a function of time. = B side2 = B (perimeter/4)2 = (0.1 ) (4.0 – 0.04 t )2/16 Tm2. d/dt B =(0.1 ) ( [2 (4.0 – 0.04 t) (- 0.04)]/16) Tm2s-1. At time zero, the magnitude of the emf is ... ................
