1. The problem statement, all variables and given/known data 1. When a 100 loop coil of wire of radius 2.00 cm is rotated in a uniform magnetic field,B=0.500T , so that it goes from maximum flux to zero flux in 0.0320 s, find the average emf induced between the terminals of the coil. 2. Relevant equations Max Flux=BAcos(0)=Change in flux E=-N change in flux/change in time 3. The attempt at a solution E=[-N(BAcos0)]/t E=[-100(0.500T pi(2.00cm2) cos 0o)]/0.0320s How do I calculate average emf? should I just divide by 0.0320s again?
