11. A coil of area 0.2 m² is placed in a magnetic field so that the normal to its area is in the direction of the field initially (left diagram), and then is turned 90⁰ (right diagram). If the magnitude of the magnetic field is: B = 0.5 T, and it takes 0.1 s to turn the coil, what is the average emf induced in the coil during this period of time? a) 1 V MA b) 2 V c) 3 V d) 4 V e) 5 V B TP + x
