A 5-Turn Square Loop (0 $\varOmega$ )Is Placed in a Magnetic Field That Makes an Angle

question 56

Multiple Choice

A 5-turn square loop (0.150 m along a side,resistance = 2.00 $\varOmega$ ) is placed in a magnetic field that makes an angle of 30 ^$\circ$ with the normal to the plane of the loop.The magnitude of this field varies with time according to B = 2.40t⁴,where t is measured in s and B in T.What is the induced EMF in the coil at t = 1.38 s?

• A)2.67 V
• B)2.87 V
• C)1.45 V
• D)2.03 V
• E)2.46 V
