A circular conducting coil with radius 2.61 cm is placed in a uniform magnetic field of 0.827 T with the plane of the coil perpendicular to the magnetic field. The coil is rotated 180° about the axis in 0.222 s. (a) What is the average induced emf in the coil during this rotation? (b) If the coil is made of copper (ρ = 1.67 times 10−8 Ω·m) with a diameter of 0.900 mm, what is the average current that flows through the coil during the rotation?



How would I start this problem?
I tried using Faraday's equation, but am getting the wrong answer
thanks
