A generator with a circular coil of 100 turns of area 2 10^-2 m^2 is immersed in a 0.01 T magnetic field and rotated at a frequency of 50 Hz, The maximum emf which is produced during a cycle is

Question

Accepted Answer

Correct answer: A. (a) Given, magnetic field, B=0.01 T Area, A=2 10^-2 m^2 Emf ,e=-N d dt=-N d dt ( BAsin ωt )=- NBAω cos ωt So, e_ max= NBAω= NBA (2 πf ) =100 0.01 2 10^-2 2 227 50=6.28 V.
