On an identity for the volume integral of the square of a vector field. Remark on a paper by A. M. Stewart
Durand, Loyal
Original · EN
Stewart has presented a position-space derivation of the identity for the volume integral of a product of two vector fields noted by Gubarev, Stodolsky, and Zakharov, and applied the results to classical electromagnetic theory. I present a simplified derivation suitable for use in undergraduate courses.
