The Generator Effect (T)

• What is meant by induced potential?

  Induced potential refers to the potential difference created across the ends of a wire when it moves through a magnetic field.
• What is the generator effect?

  The generator effect is the induction of a current in a complete circuit due to the induced potential when a wire moves through a magnetic field.
• How does the direction of the induced potential change?

  The direction of the induced potential switches when the direction of movement switches.
• What happens to the induced potential when the wire stops moving?

  The induced potential is lost when the wire stops moving.
• What factors affect the size and direction of the induced potential?

  • Strength of the magnetic field
  • Speed of the wire's movement
  • Shape of the wire (more turns in a coil increases induced potential)
• What occurs if the wire moves along the magnetic field instead of through it?

  There is no induced potential difference or current if the wire moves along the magnetic field.
• How does moving a magnet in and out of a coil of wire affect induced current?

  • Induced current is produced when a magnet moves in and out of a coil.
  • The direction of the current changes with the direction of the magnet's movement.
• What happens to the induced current when the North Pole of a magnet is inserted into a coil?

  The coil becomes a North Pole, opposing the magnet's movement.
• What occurs when the North Pole of a magnet is pulled out of a coil?

  The coil becomes a South Pole, attracting the magnet and opposing its removal.
• How does the induced current relate to energy transfer in the context of moving a magnet?

  • The induced current opposes the movement of the magnet.
  • Work is done to move the magnet, transferring energy into the current.
