| contents | The paper ``Magnetic moments in the Poynting theorem, Maxwell equations, Dirac equation, and QED", arXiv:2501.02022, by Peter J. Mohr, purports to show that Maxwell's equation, $\mathbf{\nabla}\cdot{\bf B}=0$, and Poynting's theorem require significant modications for the $\bf B$ field of a magnetic dipole. We show here that, because of critical errors in the paper, these claims are false, and that Maxwell's equation and the Poynting theorem are the same for a magnetic moment as for any other charge-current distribution. |
