This technology works due the application of electromagnets, wherein the trains levitate above the tracks, making it possible for them to move at high speeds. This type of magnet is created when electricity is passed through a conducting medium that can include ferromagnetic materials like iron, cobalt, and nickel.

I want to know how an AC electric magnet works since the polarity of an AC current changing 100 times in each second (for 50Hz mains supply) so its magnet polarity(N & S) also will changed 100 ...

electromagnetic lock work – An electromagnetic lock creates a magnetic field when energized, causing an electromagnet and armature plate to become attracted to each other strongly enough to keep a door from opening, according to HangSeng Magnetech Inc. most cases, the armature plate is on the edge of the door, while the electromagnet is wired to the building’s power grid in the wall next to the door frame.

They each use electromagnets, devices that create a magnetic field through the application of electricity. Wrecking yards employ extremely powerful electromagnets to move heavy pieces of scrap metal or even entire cars from one place to another. Your favorite band uses electromagnets to amplify the sound coming out of its speakers.
