Vector potential

Japanese: vector potential(英語表記)vectorpotential
Vector potential

…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). …

Japanese:

…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。AF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。…
