SUMMARY
The average electromotive force (emf) generated by a 15-turn cable with a diameter of 0.5 meters, when flipped 180 degrees in 2 seconds within the Earth's magnetic field of 0.5 microtesla, is calculated using the formula e = -n * r² * (ΔB/ΔT). The values used in the calculation are n = 15, ΔB = 1 microtesla, and ΔT = 2 seconds, resulting in an emf of approximately -0.468 microvolts. The alternative calculation using the area of the cable yields an emf of approximately 0.098 microvolts.
