Electrodynamics of Perfect Conductors
Miguel C. N. Fiolhais, Hanno Essén
The most general electrodynamic equations of a perfect conducting state are obtained using a variational principle in a classical framework, following an approach by Pierre-Gilles…
Mechanics, cosmology and Mach's principle
Hanno Essen
It is pointed out that recent cosmological findings seem to support the view that the mass/energy distribution of the universe defines the Newtonian inertial frames as originally s…
Meissner effect, diamagnetism, and classical physics - a review
Hanno Essen, Miguel C. N. Fiolhais
We review the literature on what classical physics has to say about the Meissner effect and the London equations. We first discuss the relevance of the Bohr-van Leeuwen theorem for…
Classical diamagnetism, magnetic interaction energies, and repulsive forces in magnetized plasmas
Hanno Essen
The Bohr-van Leeuwen theorem is often summarized as saying that there is no classical magnetic susceptibility, in particular no diamagnetism. This is seriously misleading. The theo…
New theorem of classical electromagnetism: equilibrium magnetic field and current density are zero inside ideal conductors
Miguel C. N. Fiolhais, Hanno Essen, C. Providencia +1
We prove a theorem on the magnetic energy minimum in a system of perfect, or ideal, conductors. It is analogous to Thomson's theorem on the equilibrium electric field and charge di…
Static deformation of heavy spring due to gravity and centrifugal force
Hanno Essen, Arne Nordmark
The static equilibrium deformation of a heavy spring due to its own weight is calculated for two cases. First for a spring hanging in a constant gravitational field, then for a spr…
