✦ Synopsis

ABSTRACX: Transient field build-up inside a superconductor is investigated on the basis of Maxwell's equations in conjunction with London's phenomerwlogical equations. Although

understanding of superconducting phenomena is attained only through the quantummechanical approach, it seems that the macroscopic approach resorted to leads to a qualitative as well as quantitative description of the field penetration in a superconductor.

It is shown that so-called "steady-state" conditions do not really exist for a superconductor; compatibility of the Maxwell and London equations may, however, be obtained even for very high values of the time parameter t, through a suitable approximation.
