Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A maglev train uses magnets to make the train float.
A
true
B
false
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The front corners have magnets with north poles facing out, and the back corners have magnets with south poles outward. Electrifying the propulsion loops generates magnetic fields that both pull the train forward from the front and push it forward from behind. This floating magnet design creates a smooth trip.

Detailed explanation-2: -High-speed maglev (short for magnetic levitation) trains float on air because electrified metal coils in the guideway, or track, repel large magnets attached beneath the train. Since there’s no friction, the train can go fast-more than 300 miles per hour!

Detailed explanation-3: -Maglev is a system in which the vehicle runs levitated from the guide way (corresponding to the rail tracks of conventional railways) by using electromagnetic forces between superconducting magnets onboard the vehicle and coils on the ground [10].

Detailed explanation-4: -Maglev trains work on the principle of magnetic repulsion between the cars and the track. The word maglev is actually a combination of the words “magnetic” and “levitation.” The magnetic levitation, or floating of the train, is achieved through the use of an electrodynamic suspension system, or EDS.
