A 4-step lesson. Step 1: 'Electromagnetic induction: When a conductor experiences a CHANGING magnetic field, an EMF (voltage) is induced. If the circuit is complete, this drives a current. Discovered by Faraday (1831).' Step 2: 'Ways to induce an EMF: Move a magnet near a coil, move a coil near a ma
