How Things Actually Works on Instagram: "When electric current flows through a metal wire, tiny charged particles called electrons start moving. As they collide with atoms inside the wire, several fascinating effects occur: 🔹 Heating Effect (Joule Heating) The collisions create resistance, converting electrical energy into heat. This is why wires get warm—and why bulbs and heaters work. 🔹 Magnetic Field Formation A current-carrying wire generates a magnetic field around it. This principle powe
