1. The problem statement, all variables and given/known data A rectangular coil of 80 turns has an area of 0.01m^2. It rotates @ 3000rpm about one of its in plane axes, in a uniform magnetic field having B=1.5T. Calculate the rms voltage generated. 2. Relevant equations 1 Tesla= 1 Weber/m^2. Change in flux of 1 Weber per second = 1 Volt induced. 3. The attempt at a solution (80*0.01*3000*1.5)/60 = change in flux of 60 Wb/s. ==> 60V. 60/[2sqrt(2)]=15sqrt(2)Vrms. This is not the right answer. The answer is 267Vrms.
