How strong are the magnets used in mag lev trains?



  1. 0 Votes

    The power of the magnets in maglev trains varies very wildly and very rapidly. The measure of magnetic attraction between two surfaces varies according to the distance between the surfaces CUBED, so even a very small variation in distance will require a significant change in the power output of the magnets. The magnet strength is controlled and monitored by a computerized feedback system, in order to keep the distance as constant as possible.
