London Penetration Depth

Applicable units are those of quantitykind:Length

"London Penetration Depth" characterizes the distance to which a magnetic field penetrates into a superconductor and becomes equal to 1/e times that of the magnetic field at the surface of the superconductor.

http://en.wikipedia.org/wiki/London_penetration_depth

If an applied magnetic field is parallel to the plane surface of a semi-infinite superconductor, the field penetrates the superconductor according to the expression $B(x) = B(0) \exp{(\frac{-x}{\lambda_L})}$, where $B$ is magnetic flux density and $x$ is the distance from the surface.
