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

question 25

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.
-What is the average current around the loop if the magnitude of the magnetic field is doubled in 0.4 s?
