• elecric current can be created through moving magnet in coil of wire
• induced voltage
• more loops == more voltage
• Faradays Law
  • Voltage is proportional to product of loops and rate of change of mag field
  • Loops and strength of magnet make more electricity
• Generators and AC
  • more practical to move coil than magnet
  • rotating coil in mag field
  • called a generator
  • 
  • Generators are used in most power production
