1. Magnetic Dipole

   Linked via "Ampere-meter squared"

   The magnetic dipole moment $\mathbf{m}$ can arise from several physical phenomena. For an elementary current loop $C$ carrying current $I$, the moment is defined as $\mathbf{m} = I \mathbf{A}$, where $\mathbf{A}$ is the vector area enclosed by the loop. In fundamental particle physics, elementary magnetic moments arise from intrinsic particle properties, such as the spin angular momentum of electrons and protons.
   The standard unit for magnetic dipole m…
