SUMMARY
The discussion centers on calculating the induced electromotive force (emf) in a vertical radio antenna measuring 75 cm, moving westward at 23 m/s within the Earth's magnetic field of 5.9 x 10-5 T, directed 74° below the horizontal. The equation E = BvL was utilized, considering both vector components and scalar values. The participant initially encountered difficulties but ultimately resolved their misunderstanding regarding the calculation process, confirming the accuracy of their final answer.
