Methods:
- Move a conductor through a magnetic field
- Move a magnet into/out of a coil
- Change the magnetic field through a coil
Key requirement: The magnetic field through the conductor must be CHANGING. No change = no induced voltage.
To increase induced voltage:
- Move the magnet/conductor faster
- Use a stronger magnet
- Use more turns on the coil
To reverse the direction of induced current:
- Move in the opposite direction
- Reverse the magnetic field (flip the magnet)
