Work Step by Step

Recall that $\epsilon_{0}=NBA(2\pi\nu)$ where $\epsilon_{0}$ is the maximum emf, N is the number of turns, B is the magnetic field, A is the area, and $\nu$ the frequency. Thus, we find: $B= \frac{\epsilon_{0}}{NA\times2\pi\nu}=\frac{5500V}{150\times0.85m^{2}\times2\pi \times60 Hz}$ =0.11 T
