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 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?
A) 2.8 × 10-³ A,clockwise
B) 4.5 × 10-³ A,clockwise
C) 4.5 × 10-³ A,counterclockwise
D) 9.0 × 10-³ A,clockwise
E) 9.0 × 10-³ A,counterclockwise
