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 Ωm) 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
