"A student tried to make an AC generator consists of a coil of one turn, and cross sectional area of (7.54 × 10^-3 m²\$7.54 × 10^{-3} m²\$), and rotates in magnetic flux density (2.5 × 10^-2 T\$2.5 × 10^{-2} T\$), and when it was taken out of the magnetic flux in 1.256 × 10^-3\$1.256 × 10^{-3}\$ sec an induced emf of 1.5V has been generated." That was the description of a generator, then it asked whether that generator is practical or not? The answer was "No" without an explanation, so could you please explain it for me?
