the generator effect

• when conductors and magnetic fields interact, a potential difference is induced . this is called the generator effect
• the potential difference may be induced by:

  • an electrical conductor moving relative to a magnetic field
  • a change in magnetic field around a conductor
• increasing the speed of the movement or the size of the magnetic field will increase the size of the induced potential difference
• an induced current generates a magnetic field that opposes the original change which produces it
