A coil of 160 turns and area 0.20 m2 is placed with its axis parallel to a magnetic field of initial magnitude 0.40 T (so that the plane of the coil is perpendicular to B). The magnetic field changes uniformly from 0.40 T in the +x direction to 0.40 T in the ‒x direction in 2.0 s. If the resistance of the coil is 16 Ω, at what rate is thermal energy generated in the coil? What is the direction of the induced current? You must draw a figure to define the current direction.
