A Flexible, Circular Conducting Loop of Radius 0 $\varOmega$ Lies in a Uniform Magnetic Field of 0

question 42

Multiple Choice

A flexible, circular conducting loop of radius 0.15 m and resistance 4.0 $\varOmega$ lies in a uniform magnetic field of 0.25 T. The loop is pulled on opposite sides by equal forces and stretched until its enclosed area is essentially zero m², as suggested in the drawings. It takes 0.30 s to close the loop.
-Determine the magnitude of the emf induced in the loop.

• C)1.8 × 10² V
• D)5.9 × 10^-2 V
• E)5.9 × 10² V
