A magnetic field in a vacuum cannot penetrate a volume with infinite conductivity.
2.
This effect cannot be explained by infinite conductivity alone.
3.
Superconductivity means infinite conductivity, for example.
4.
But as the ball expanded it would rapidly cool, losing its infinite conductivity as well as its electromagnetic knot, and thereby destroying itself.
5.
A black hole singularity has zero volume, and thus infinity density, just like a superconductor has zero resistance, and thus infinite conductivity.
6.
Chapman and Bartels ( 1940 ) illustrated this concept by postulating a plate with infinite conductivity placed on the dayside of a planet s dipole as shown in the schematic.
7.
For example : optical nonlinearities can be neglected for low field strengths; material dispersion is unimportant when frequency is limited to a narrow perfect metals with infinite conductivity ( forming hard barriers with zero skin depth of field penetration ).
8.
Only from those concrete relative terms could we manipulate the math and speak in terms of the infinite conductivity of the hose, but that would be like the infinite applelessness of the empty lunch bag, a derived formal infinity, not a real concrete infinity.

:: : : : It seems very similar to the Meissner effect in superconductors : " Note that field expulsion ( or cancellation ) implies infinite conductivity, but that infinite conductivity does not imply field expulsion, because if a material develops only infinite conductivity below its transition temperature, that infinite conductivity will " freeze in " whatever magnetic field was present as the transition temperature was reached ."
