1. The problem statement, all variables and given/known data A closely wound rectangular coil of 95.0 turns has dimensions of 29.0 cm by 40.0 cm. The plane of the coil is rotated from a position where it makes an angle of 39.0 degrees with a magnetic field of 1.60 T to a position perpendicular to the field. The rotation takes 0.120 s. What is the average emf induced in the coil? 2. Relevant equations 3. The attempt at a solution ε=ΔB/Δt*(A*cos 39°) ε=1.6/.120*(.116*cos39) =1.20 This is the wrong answer!
