Physics Uncovered on Instagram: "High voltage alternating current can transfer energy in very selective ways depending on the material it passes through. When AC flows through Dr. Irwin Moon’s copper coil, it creates a rapidly changing electromagnetic field. Materials placed inside that field respond differently based on their electrical resistance, conductivity, moisture content, and molecular structure."

This is helicopter-supported live-line transmission maintenance, one of the most demanding operations in modern aviation. Crews service high-voltage power lines carrying up to hundreds of kilovolts while they remain fully energized. By equalizing electrical potential between the helicopter, technician, and conductor, workers can safely inspect and replace critical components without shutting down the grid. This matters because it keeps entire regions powered continuously, even across remote terr
