Maxwell's Equations and Electromagnetic Waves. Michael Fowler, Physics Department, UVa.
There are various mathematical descriptions of the electromagnetic field that are used in the study of electromagnetism, one of the four fundamental forces of nature. In this article three approaches are discussed, generally the equations are in terms of electric and magnetic fields, potentials...
To remember the integral form of Maxwell’s Equation No. 1, consider that a charge q, enclosed in a volume, must be equal to the volume charge density, r, times the

This equation shows that the magnetic field is increasing at a rate of 0.019 T/s.
The "integral form" of the original Ampère's circuital law is a line integral of the magnetic field around any closed curve C (This closed curve is arbitrary but it must be closed, meaning that it has no endpoints).

Both the electric field and the magnetic field are perpendicular to the direction of travel x. The symbol c represents the speed of light or other electromagnetic waves.
This is the case portrayed in Figure 2 where a stationary conducting loop is in a time varying magnetic B field. Equation (1.3) becomes.
