Electromagnetic knots and the magnetic flux in superconductors
... Consider a magnetic field B(r, t) defined in every point r of the three– dimensional space at every time t. Such magnetic field can be given in terms of a vector potential but, alternatively, it can be defined through the magnetic lines at every time. These lines are the solutions of the ...

... incompressible and massless fluid. Maxwell separated between physical quantities of two kinds, “intensity”, like the gradient of the pressure, and “quantity”, like the velocity of mass. They obeyed a linear relation involving a parameter of the medium. Thus, for magnetism (electricity) the intensity ...

... (note this energy splitting is small ~10-5 eV in H). We can estimate the splitting using the Bohr model to estimate the internal magnetic field. For atomic electrons, the relative orbital motion of the nucleus creates a magnetic field (for l 0). The electron spin can have ms = ±1/2 relative to the ...
