Basic law in Magnetostatics
... Ampere’s force law describes an “action at a distance” analogous to Coulomb’s law. In Coulomb’s law, it was useful to introduce the concept of an electric field to describe the interaction between the charges. In Ampere’s law, we can define an appropriate field that may be regarded as the means by w ...
