The motor affect

  • what is the motor effect
    when two magnets interact, a magnetic force (of attraction/repulsion) is felt
    so a magnet and a wire must also exert a force, as the two magnetic fields will also interact
    • the magnetic field around a wire is circular, but the magnetic field between two magnets is straight
    • when the two interact, the wire is pushed away from the field between the poles
  • what is Flemings left hand rule
    when you have: force, field, current
    each direction is 90* to each other
    (current is conventional current - moves in the opposite direction to the electrons)
  • what is magnetic flux density measured in
    tesla
