The Figure Shows a Uniform, 3 $\varOmega$ And a Radius of 0

question 33

Multiple Choice

The figure shows a uniform, 3.0-T magnetic field that is normal to the plane of a conducting, circular loop with a resistance of 1.5 $\varOmega$ and a radius of 0.024 m. The magnetic field is directed out of the paper as shown. Note: The area of the non-circular portion of the wire is considered negligible compared to that of the circular loop.
-If the magnetic field is held constant at 3.0 T and the loop is pulled out of the region that contains the field in 0.2 s, at what rate is energy dissipated in R?

• A)1.8 × 10^-2 W
• B)3.6 × 10^-2 W
• C)3.8 × 10^-3 W
• D)2.7 × 10^-4 W
• E)4.9 × 10^-4 W
