B Electromagnetic force

  1. Sep 10, 2016 #1
    Electricity flowing through a wire creates it's own magnetic field. So when the electricity is flowing through a wire, it's magnetic field works AGAINST the generator, slowing it down.

    So is there is any way to stop slowing down process without increasing amount of current ??

    Increase the mechanical input to the generator when it slows down (look up 'ALFC in power system'). For a steady speed, electrical power output=mechanical power input (ideally).
