The coil shown in the figure has a resistance of 3.0 ?, 2 turns, a cross-sectional area of 0.20 m2, and a field (parallel to the axis of the coil) with a magnitude given by B(t) = (4.0 + 3.0t2) T, where t is in s. What is the value of the induced current in the wire at t=3.5 s? Does this current flow from point A to point B or from point B to point A? (Answer: 2.8 A, B to A)
