🧲 Effects of Electric Current

Electricity can make magnetism, and magnetism can make electricity! Explore the electromagnet, motor and generator.

🧠 The Big Idea

Magnetic effect: current in a wire creates a magnetic field. Coil it around iron → a strong electromagnet (more current = stronger).
Motor: a current-carrying coil in a magnetic field feels a force and spins — electrical energy → motion. (Fans, mixers, EVs. 🚗)
Generator / induction: moving a magnet near a coil induces a current — motion → electricity. (This is how power stations work! 🏭)
