An electric generator consists of turns of wire formed into a rectangular loop a = 0.05 m by b = 0.03 m placed entirely in a uniform magnetic field with magnitude Bo=2.5-T. What is the maximum value of the emf produced when the loop is spun at w=1000 rev/min about an axis perpendicular to B?
Answer is suppose to be 196 but i dont understand how to get it.
yes 500 turns

How many turns of wire? I think they have to be n=500, haven’t they?
Emax=nabB₀ω
where ω=2πw/60 rad/s
Edit:
ω=2π*1000/60=100π/3
Emax=500*0.05*0.03*2.5*100π/3
Emax=196.35 V
