A circular coil of $1000$ turns each with area $1\ \text{m}^2$ is rotated about its vertical diameter at the rate of one revolution per second in a uniform horizontal magnetic field of $0.07\ \text{T}$. The maximum voltage generated will be ______ V.
Numerical value type. Enter your answer.
Answer: 440
$$\varepsilon_0 = NBA\omega = 1000\times0.07\times1\times2\pi \approx 440\ \text{V}$$
