Question

collect pictures and information about maglev trains. why friction does not reduce their speed?

Answer 1

Maglev is the short form of MAGNETIC LEVITATION, and that gives the clue. So trains float on a cushion of air ( 4 inches/10 cm above) and hence no friction, no moving parts like wheels and bogies, no rail track etc which are the limitations of conventional track to attain higher speed. Like the " Indian Sadhus" of the historic variety, these trains levitate on thin air upon starting the train.
