∈ max = BAN ω =0.07 × 1 × 103 × 2 π =140 π ≈ 440

Q. A circular coil of $1000$ turns each with area $1 m^{2}$ is rotated about its vertical diameter at the rate of one revolution per second in a uniform horizontal magnetic field of $0.07 T$ . The maximum voltage generation will be ______ $V$ .

$\in_{m a x} = B A N ω$
$= 0.07 \times 1 \times 1 0^{3} \times 2 π$
$= 140 π \approx 440$
