  • Electromagnetic Induction
    • Dynamo Effect
      • Conductor in motion  in a magnetic field is inducing electricity
        • Get more electricity add a magnet and a coil
          • Get even more add a stronger magnet and more motion
    • Transformers
      • Structure - coil around an iron
      • AC produced in primary coil
        • Causes alternate magnetic field
          • Goes around iron core into secondary coil
            • Change in magnetic field in secondary coil induces potential difference
      • Step Up - more coils Voltage goes up Current goes down
      • Step Down - less coils
