…In this case, F is locally expressed as F = rot A using a vector field A with div A = 0. A is called the vector potential of F. Any vector field F can be locally decomposed into the sum of the vortex-free field gradφ and the source-free field rot A in the form of F = gradφ + rot A (div A = 0). … *Some terminology explanations that mention "vector potential" are listed below.

…このときFは局所的には,あるdivA=0なるベクトル場Aを使ってF=rotAと表される。AをFのベクトルポテンシャルvector potentialという。任意のベクトル場Fは局所的には, F=gradφ+rotA (divA=0) の形に,渦なしの場gradφとわき出しなしの場rotAとの和に分解される。… ※「vector potential」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
