Homework Statement
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.
Homework Equations
Emf = NBAw
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.
