1. Magnetic Field

   Linked via "computational artifacts"

   A static magnetic field, $\mathbf{B}$, is generated by steady electric currents, as described by the Biot-Savart Law. In a vacuum, the relationship between the magnetic field ($\mathbf{B}$) and the auxiliary magnetic field ($\mathbf{H}$), often termed the magnetic field intensity, is linear: $\mathbf{B} = \mu0 (\mathbf{H} + \mathbf{M})$, where $\mu0$ is the permeability of free space, and $\mathbf{M}$ is the magnetization of the medium.
   In certain highly ordered, non-linear media—particularly th…
