A 5-Turn Square Loop (10 Cm Along a Side, Resistance

question 12

Multiple Choice

A 5-turn square loop (10 cm along a side, resistance = 4.0 Ω) is placed in a magnetic field that makes an angle of 30° with the plane of the loop. The magnitude of this field varies with time according to B = 0.50t2, where t is measured in s and B in T. What is the induced current in the coil at t = 4.0 s?

• A)25 mA
• B)5.0 mA
• C)13 mA
• D)43 mA
• E)50 mA
