  channel of a mos is the layer formed between the drain and source and is of the same type of that of drain and source
  
  its length is inversely proportional to to the current Id and as it decreases the current increases
  in NMOS the applied voltage Vgs increases more negative ions get concentrated in between drain and source which in turn reduces channel length similar thing happens with PMOS
  its called channel length modulation effect
