At what frequency should a 200-turn, flat coil of cross sectional area of 300. 0 cm2 be rotated in a uniform 30. 0-mt magnetic field to have a maximum value of the induced emf equal to 8. 0 v?.

The frequency of the coil of f cross-sectional area of 300. 0 cm²,  for a maximum value of the induced emf equal to 8. 0 v is 7.1 Hz.Since we are provided with several turns,  n = 200, the cross-sectional area of the coil which is  300 cm² (300 x 10⁻⁴ m²), and the magnetic field of 30 x 10⁻³ T. since we know, the  Maximum induced emf is E = NBAωwhere ω is angular velocity which is equal  to 2πf, N is the number of turns, B is the magnetic field and A is the cross-sectional area, E is  the emf. substituting the value of  w to  2πf, we get E = NBA2πf,  were f is the frequency  =>f = E / (NBA2π)=>f = 8 / (200 x 30 x 10⁻³ x 300 x 10⁻⁴ x 2 x 3.142)=>f = 7.073 Hz=>f = 7.1 HzTo know more about  frequency refer to the link https://brainly.com/question/5102661?referrer=searchResults.#SPJ4
