A Linear Structure from Magnetic-Dipole Systems and Its Geometry

Abstract: We investigate a class of algebras on $\mathbb{R}^3$ arising and generalized from the algebraic structure of magnetic gradient fields induced by systems of synchronous magnets with identical dipole moments (i.e., $\mathbf{M}_i=\mathbf{M},\,\forall i$). We show that when there is a $2$ dimensional sub-algebra, the linear structure associated to such an algebra admits a certain type of decompositions, which allows the locating of the dipole moment $\bar{\mathbf{M}}$ that yields the strongest translational force(s) on a test magnet $\mathfrak{m}$. Upper bounds to the strength of this magnetic force are then established.
