How do maglev trains work?

what is a maglev train the word maglev

comes from the combination of magnet and

levitation maglev trains take advantage

of a physics principle that says - like

magnetic poles will repel each other

for instance the North Pole of one

magnet and the North Pole of another

magnet pointed at each other will push

away from each other but if we put a

South Magnetic Pole and a North one

together they will attract maglev trains

take advantage of both these ideas not

only to provide levitation but also

propulsion in order for the Train to

levitate the two light poles are forced

to repel each other like the magnets

shown here to provide propulsion the

Train is outfitted with a North and

South Pole magnet so long as that the

track also has north and south pole

magnets whose poles can be switched

quickly as the poles are switched and

trains attracted to and then repelled by

the same magnet the status of the pole

switch the best the train goes now you

may be asking something why is all this

necessary we already have trained maglev

trains offer one key advantage over

typical rail and high-speed rail and

that is minimal resistance

unlike other trains that must stay

connected to the rail maglev trains can

float above the rail only having to

overcome air resistance the only problem

with maglev trains are that they are

very expensive costing between 50 and

200 million dollars per mile

compare that with reports a two million

dollars for high-speed rail and a meager

two and a half million dollars for

typical rail service maglev trains still

may have a home it's the Hyperloop
