... led to some misinterpretations of his treatment vis a vis earlier work. In particular, his formulation of the balance law for energy and the Clausius-Duhem inequality are seemingly non-standard, and their consistency with alternative ideas recently revisited by Ericksen has been called into question ...

Magnetic Fields
... Origin of Magnetic Fields Recall that the strength of an electric field E was defined as the electric force per unit charge. Since no isolated magnetic pole has ever been found, we can’t define the magnetic field B in terms of the magnetic force per unit north pole. We will see instead that magneti ...
