1. The problem statement, all variables and given/known data A generator has a 170-turn square coil, 5 cm on a side. Find the peak emf in this coil when it's rotating at 90.0 Hz in Earth's field, 5*10^-5 T Express your answer to one significant figure and include the appropriate units. 2. Relevant equations Emf = NBAw 3. The attempt at a solution N = 170 B = 5*10^-5 A = 0.05^2 = 0.0025m^2 w = 2*pi*f = 565.49 subbing in, emf = 0.012V BUT. mastering physics is telling me its wrong.
