  Meissner effect
It was discovered by Walter Meissner[?] and Robert Ochsenfeld[?] in 1933 and it is often referred to as perfect diamagnetism or the Meissner-Ochsenfeld effect.
The Meissner effect is one of the defining features of superconductivity, and its discovery served to establish that the onset of superconductivity is a phase transition.
Superconducting magnetic levitation is due to the Meissner effect (which repels a permanent magnet) and flux pinning[?], which stops the magnet from sliding away.

 CIRL - Pioneers in Electricity and Magnetism: Walther Meissner
Fritz Walther Meissner was born on December 16, 1882, in Berlin, Germany.
Meissner accepted a position at the Physikalisch-Technische Reichsanstalt, a scientific research institute founded by Hermann von Helmholtz, in 1887.
This phenomenon, commonly known as the Meissner effect or the Meissner-Ochsenfeld effect, is related to the generation of screening currents along the surface of the superconductor that are able to cancel out the applied magnetic field.

 Superconducting optically reconfigurable magnetic device - Patent 5287302
In addition to the Meissner effect or magnetic properties related uses of superconductivity, there are two varieties of superconductors which are of concern in the present invention; these are the so termed Type I and Type II varieties.
The Meissner effect, as is particularly of interest in the present invention, has been defined as the expulsion of magnetic flux from the interior of a superconducting material when it is cooled in a magnetic field to below the critical temperature, near absolute zero, at which the transition to superconductivity takes place.
In "Hard" Type II superconductors the extent of the Meissner effect transition region is minimized by the use of flux pinning mechanisms which tend to situate the flux vortices and reduce the kinetic generation of electrical resistance.

 How Does A Superconductor Work?   (Site not responding. Last check: 2007-10-13)
n 1933 it was determined by Walter Meissner and Robert Ochsenfeld that superconductive materials can repel magnetic fields.
They determined that when a material was penetrated with a magnetic field, in its' superconductive state, it would create a current inside the superconductor.
This was an extraordinary discovery and thus the term "Meissner Effect" was coined to describe this unexpected occurrence.

 Research - News Centre: The long and winding road
The slow and sometimes very intermittent progress of research during the last century, nevertheless, brought a number of advances in the fundamental knowledge of the superconductor phenomenon and its unique properties.
It was in 1933 that the Germans Walter Meissner and Robert Ochsenfeld demonstrated the surprising diamagnetic effect (now known as the Meissner effect) by which a current passing through a superconductor exercises a strong repelling force on an external magnetic field.
The Meissner effect has consequently become the best way of testing whether a material superconducts or not.

(Named for Walter Meissner.) This is a classic hallmark of superconductivity and can actually be used to levitate a strong rare-earth magnet.
However, having one-dimensional geometry, this wire does not exhibit the Meissner effect, except when configured as a closed loop.
The Meissner effect cannot be confirmed in them, but strong (giant) diamagnetism is in evidence.

 Conductors in Static Electric Field
The reason behind this is that in a superconductor the induced currents exactly mirror the field that would have otherwise penetrated the superconducting material - causing the magnet to be repulsed.
This magnetic repulsion phenomenon is called the Meissner Effect and is named after the person who first discovered it in 1933.
Type I superconductors exhibit a very sharp transition to a superconducting state, while type II superconductors transition from a normal to a superconducting state is gradual across a region of "mixed state" behavior.
