← ScienceWhich mechanism allows superconducting magnets to levitate trains?
A)Meissner effect creating magnetic repulsion✓
B)Eddy current induction causing drag
C)Flux pinning preventing field movement
D)Quantum entanglement enabling direct transfer
💡 Explanation
The Meissner effect expels magnetic fields from the superconductor, giving a repulsive force between the train magnets and the track. Because of this, the train levitates rather than experiencing friction. Other options do not correctly reflect the mechanism maintaining distances.
