Question

flexible loop has a radius of r = 20.3 cm and it is inside a uniform magnetic field of B = 0.515 T. The loop is grasped at points P and Q and stretched until its area is zero. It takes 212 ms to close the loop. ·B What is the magnitude of the average induced electromotive force in the loop during the stretching process? 3.14x10-1 v You are correct. Previous Tries Complete the following sentence: During the stretching process described above... O ...no current flows o current flows clockwise o . current flows counter clockwise. o.. current flows in different directions at different stages of the process. Submit Answer Incorrect. Tries 1/2 Previous Tries

Explanation / Answer

Option (C) will be correct. A COUNTER CLOCK WISE CURRENT is induced.

The current induced because area is decreasing and hence number of flux passing through it also decreasing .As per Lenz's law, CURRENT must be induced in COUNTER CLOCK WISE direction to support the strength of flux and tries to oppose their decrement due to decreasing area.
