SUMMARY
This discussion focuses on applying Faraday's Law to determine the rate of change of the radius of a circular loop in a uniform magnetic field to achieve zero induced electromotive force (emf). The loop has a radius of 12 cm and is subjected to a magnetic field of 0.5 T, which decreases at a rate of -0.01 T/s. The initial emf calculated is 0.01 V, and the initial magnetic flux is 0.0023 Wb. The solution requires balancing the rate of change of the magnetic field with the change in the loop's radius to cancel the induced emf.
