why maglv ( Magnetic train ) make noise in high speeds ?

Wind noise? Levitation magnets commutating at audible
frequencies when time-over-target is short enough?
Everything makes noise when you go fast, pretty much.

I saw a tv segment where an airplane glided overhead at low altitude, with no engines on. It still made noise like a jet, simply by moving through the air at high speed.

Some maglev rails have gaps between them.. they can be the cause of the sound.

Acoustics produced in the air gap is sufficient to produce audible noise
