In the figure, a wire and a 10 ohm resistor are used to form a circuit in the shape of a square, 20 cm by 20 cm. A uniform but non-steady magnetic field is directed into the plane of the circuit. The magnitude of the magnetic field is increased from 0.6 T to 1.8 T in a time interval of 44 ms. The average induced current and its direction through the resistor, in this time interval, are closest to:
