The Figure Shows a Uniform, 3 Ω\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 Ω\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.
