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

Question 40

Multiple Choice

A 5-turn square loop (0.150 m along a side,resistance = 2.00 Ω\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 current in the coil at t = 1.25 s?


A) 1.47 A
B) 1.23 A
C) 0.913 A
D) 0.527 A
E) 0.351 A
