Classical electromagnetic theory explains how electromagnetic forces interact with charges and currents based on a Newtonian model.
Here's the poll question:
In 1820 _________ discovered that when an electric current flows in a conductor a magnetic field is produced. Less than a decade later, ________ established the relationship between current and the magnetic field. In 1831, ________ discovered that a changing magnetic field causes current to flow in a closed electric circuit linked by a magnetic field. _________demonstrated that there is a relationship between a changing magnetic field and the induced current. ________ proved that magnetic poles cannot exist in isolation. In 1865, _______ unified electromagnetism theory in four equations that completely describe the behavior of electric and magnetic fields.
