As Shown in the Figure,a Large Round Loop of 269 78.0 A. 78.0 \mathrm {~A} \text {. }

Question 97

Short Answer

As shown in the figure,a large round loop of 269 turns and radius 67.0 cm carries a current of I = 78.0 A. 78.0 \mathrm {~A} \text {. } A small square loop of 31.0 turns and 1.00 cm on a side is placed at the center of the large loop.If the current in the large loop drops to 0.00 A in 0.0470 s,find the induced emf in the small loop.The square loop is small enough that you can assume that the B⃗\vec { B } field in its region is uniform and equal to the B⃗\vec { B } field at the center of the round loop.(μ0 = 4π × 10-7 T ∙ m/A) As shown in the figure,a large round loop of 269 turns and radius 67.0 cm carries a current of I = 78.0 \mathrm {~A} \text {. } A small square loop of 31.0 turns and 1.00 cm on a side is placed at the center of the large loop.If the current in the large loop drops to 0.00 A in 0.0470 s,find the induced emf in the small loop.The square loop is small enough that you can assume that the \vec { B } field in its region is uniform and equal to the \vec { B } field at the center of the round loop.(μ<sub>0</sub> = 4π × 10<sup>-7</sup> T ∙ m/A)
