Meissner effect(redirected from Meissner-Ochsenfeld effect)
Also found in: Encyclopedia.
The effect whereby magnetic fields are excluded from a superconductor's interior if the superconductor is below a critical temperature, since introducing a magnetic field immediately creates electric currents in the superconductor that cancel the magnetic field. The Meissner effect is responsible for the diamagnetic properties of superconductors.
[After Fritz Walther Meissner (1882-1974), German physicist who discovered it in collaboration with Robert Ochsenfeld (1901-1993), German physicist.]
(General Physics) physics the phenomenon in which magnetic flux is excluded from a substance when it is in a superconducting state, except for a thin layer at the surface
