- 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
- Get more electricity add a magnet and a coil
- Conductor in motion in a magnetic field is inducing electricity
- 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
- Goes around iron core into secondary coil
- Causes alternate magnetic field
- Step Up - more coils Voltage goes up Current goes down
- Step Down - less coils
- Dynamo Effect
