Question 12 (15 marks) Consider a horizontal circular flat coil having 10 turns and an area of 3.0 m² in Figure Q12. The circuit is perpendicular to a uniform magnetic field pointing out of the paper. The magnetic field strength increases from 1.0 T to 3.0 T in 0.05 s. (a) What voltage will appear across terminals A and B? (5 marks) (b) From the perspective of looking down on the coil, the wire winds clockwise from B to A. What is the direction of the induced magnetic field? Justify your answer. (3 marks) (c) What is the direction (clockwise or anti-clockwise) of the induced current? Justify your answer. (3 marks) (d) Which terminal has the higher potential, A or B? Justify your answer. (4 marks) Figure Q12
