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?.

= 7.1 HzBy Emf = -N∆(BA)/∆t 8 = [200 x 30 x 10^-3 x 300 x 10^-4]/∆t ∆t = 0.023 sec n = 1/T = 1/0.023 = 44.44 Hzangular frequency = 44.44/2pi  = 7.1 Hzyou can learn more through link below:https://brainly.com/question/11514007#SPJ4
