Faraday's Law: As shown in the figure, a wire and a 10-? resistor are used to form a circuit in the shape of a square with dimensions 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 steadily decreased from 2.70 T to 0.90 T in a time interval of 96 ms. What is the induced current in the circuit, and what is its direction through the resistor?
A. 75 mA, from b to a B. 45 mA, from b to a C. 75 mA, from a to b D. 45 mA, from a to b E. 110 mA, from a to b
