What causes a maglev train to hover above the track

A maglev train hovers above the track due to a combination of electromagnetic forces and magnetic levitation technology. The train is propelled and suspended above the track by powerful magnets that create a magnetic field. This magnetic field repels the train from the track, causing it to float and glide smoothly along the guideway without any friction. This allows the train to achieve high speeds and operate with minimal noise and vibration.
