Why Do Power Lines Buzz?

The video explains the buzzing sounds from power lines and transformers. It covers the causes of transformer hum, including stray magnetic fields and magnetostriction, and discusses how the intensity of the hum is related to voltage. The video also explores corona discharge in power lines, which causes a buzzing sound and a bluish glow, similar to a miniature lightning strike.
