The 4 Equations above are known as Maxwell’s Equations. Since Maxwell contributed to their development and establishes them as a self-consistent set. Each differential Equation has its integral part. One form may be derived from the other with the help of Stoke’s theorem (or) Divergence theorem.

**word statements of the field Equations:-**

A word statement of the field Equations is readily obtained from their mathematical statement in the integral form.

1. .

i.e, The magneto motive force ( is m.m.f)around a closed path is equal to the conduction current plus the time derivative of the electric displacement through any surface bounded by the path.

2. .

The electro motive force ( is e.m.f)around a closed path is equal to the time derivative of the magnetic displacement through any surface bounded by the path.

3. .

The total electric displacement through the surface enclosing a volume is equal to the total charge within the volume.

4. .

The net magnetic flux emerging through any close surface is zero.

the time-derivative of electric displacement is called displacement current. The term electric current is then to include both conduction current and displacement current. If the time-derivative of electric displacement is called an electric current, similarly is known as magnetic current, e.m.f as electric voltage and m.m.f as magnetic voltage.

the first two Maxwell’s Equations can be stated as

- The magnetic voltage around a closed path is equal to the electric current through the path.
- The electric voltage around a closed path is equal to the magnetic current through the path.
