Electromagnetic duality replaces the electric dipole by for a magnetic dipole moment . Therefore
This is the magnetic-dipole term of the multipole radiation expansion.
Multipole radiation 2026-10-14
Multipole radiation expands radiation from localized time-dependent sources into electric and magnetic multipoles. Electric dipole radiation is the leading electric term, while magnetic dipole radiation and higher electric multipoles contribute when the leading term vanishes or higher precision is needed.
