When an electric current flows through a wire, it creates a magnetic field around the wire - this is called magnetic induction. The magnetic field forms circles around the wire, and the direction of the field depends on which way the current is flowing. If you coil the wire into a loop or a spiral (called a solenoid), the magnetic effect becomes even stronger. #science #physics #facts #learning #explained
