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

question 32

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,20 cm by 20 cm.A uniform but nonsteady magnetic field is directed into the plane of the circuit.The magnitude of the magnetic field is decreased from 1.50 T to 0.50 T in a time interval of 63 ms.The average induced current and its direction through the resistor,in this time interval,are closest to

• A) 63 mA, from b to a.
• B) 38 mA, from b to a.
• C) 63 mA, from a to b.
• D) 38 mA, from a to b.
• E) 95 mA, from a to b.
