Question

A flexible, circular conducting loop (with 615 turns) of radius 0.18 m and resistance 6 ohms lies in a uniform magnetic field of 0.9 T. The loop is pulled on opposite sides by equal forces and stretched until its enclosed area is essentially zero m², It takes 0.38 s to close the loop. At what rate is heat generated in the loop, in watts? Please round your answer to the nearest whole number (integer).
