We’ve seen that modern electromagnetic theory is a field theory. The existence of electric and magnetic fields explains electric and magnetic phenomena. Electric charge (and its moving form, current) is both the source of these fields and the recipient of force from these fields. Electromagnetic theory, then, has two aspects: charge creates electric and magnetic fields, and electric and magnetic fields apply force to charge. In the last four chapters, we dealt with the first of these aspects in static and steady situations. We showed how charge creates electric fields and how current creates magnetic fields.
In this chapter, ...
