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

-At what rate is heat generated in the loop?

-At what rate is heat generated in the loop?

Quizplus · Accepted Answer

The correct rate of heat generation in the loop is 8.7 × 10⁻⁴ W, as it is the only option that fits the typical range for such a scenario.
