Electrical Simplified on Instagram: "Why Do Transformers Make Noise? Magnetostriction causes transformer cores to physically vibrate under alternating magnetic fields, producing the familiar humming sound in substations and power equipment. A simple concept with powerful real-world effects. 🔗 Explained simply at: www.electricalsimplified.com"

Electrical Simplified on Instagram: "Ever wondered why transformers hum? 🔊 That sound comes from magnetostriction — when the transformer core slightly expands and contracts as it’s magnetized.
