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

question 59

Multiple Choice

A flexible, circular conducting loop of radius 0.15 m and resistance 4.0 Ω\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.
