🔧 Why Transformer Produces Humming Noise — Full Technical Explanation (Pointwise) 1️⃣ Magnetostriction of Core Laminations (Primary Reason) When AC voltage is applied, the magnetic flux density (B) in the transformer core changes at 2 × supply frequency (100 Hz for 50 Hz system). Due to this, core laminations undergo minute physical expansion and contraction known as magnetostriction. This cyclic expansion → vibration → humming sound. Higher flux density → more magnetostriction → more humming.
