As Shown in the Figure, a Wire and a 10-Ω

question 71

Multiple Choice

As shown in the figure, a wire and a 10-Ω 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
