Etymology

Origin of Meissner effect

After German physicist Fritz Walther Meissner (1882–1974), who contributed to a description of the effect in 1933

Example Sentences

This so-called critical current behavior and the Meissner effect are the two key features of superconductors.

From Science Daily

The levitation, the scientists said, demonstrated the Meissner effect, which ensures zero magnetic field inside a superconductor.

From New York Times

One such test is for the Meissner effect: because a superconductor expels magnetic fields, it repels other magnets, producing an iconic levitating effect.

From Scientific American

The South Korean researchers provided a video of what they say is LK-99 exhibiting the Meissner effect, but superconductors aren’t the only things that float above magnets—graphite, for example, also levitates.

From Scientific American

That phenomenon, known as the Meissner effect, is considered to be definitive evidence of a superconductor.
