If you rotate a 45 turn rectangular loop that is 0.2 m by 0.6 m in a uniform magnetic field of 1 tesla, turning at a rate of 28 revolutions (2? radians) per second, what is the maximum emf?
Homework Answers
induced emf is defiend as the rate of change of magnetic flux
in mathematical form,
induced emf e = NABW
where A = area = l* b
N = no. of tunrs
dB/dt = rate of change of amgnetic flux
so emf e = 45* 0.2* 0.6* 1 * 28 * 2*3.14
emf e = 949.536 Volts
