Remarks on balance laws in electromagnetism

Angelo Morro (1993)

Similarity:

Two aspects of balance equations in electromagnetism are considered. First, concerning Faraday's law and Ampere's law it is emphasized that appropriate treatment of the time derivative of an integral over a time-dependent surface eliminates ambiguities occurring in various presentations of the subject. Second, standard forms of energy balance are shown not to be equivalent in the case of materials with memory.

Global free boundary problem for incompressible magnetohydrodynamics

Piotr Kacprzyk

Similarity:

We consider the motion of incompressible mhd in a domain bounded a free surface. In the external domain there exists an electromagnetic field generated by some currents which keeps the mhd flow in the bounded domain. On the free surface transmission conditions for the electromagnetic fields are imposed. For sufficiently small initial velocity and vanishing external force the global existence is proved. The L₂-approach is used. This helps us to treat the transmission conditions. ...
