Question 8 (1 point) A rectangular coil (3 turns, 1m x 2m, R = 4 ohms) is rotating in a uniform magnetic field. At t = 0 s, the normal makes an angle of 60 degrees with the field. At t = 0.1 s, the normal to the coil is perpendicular to the magnetic field. An average emf of 3.0 V is induced in the coil. Find the magnitude of the magnetic field at the location of the coil. a. 0.2 T b. 0.5 T c. 0.1 T O d. 0.4 T e. 0.7 T
