friction quits its job when magnets do the lifting.
means a technology that suspends and moves objects using magnetic fields instead of wheels or rails contact.
from rooted in electromagnetism theory from the 1800s, but the term maglev entered public vocabulary in the 1960s when engineers started building trains that float on magnetic repulsion instead of rolling on tracks.
