The combination of equations 3 and 4 can explain electromagnetic wave (such as light) which can propagate on its own. The combination says that a changing magnetic field produces a changing electric field, and this changing electric field produces another changing magnetic field.

Maxwell’s equations, which appear on the front of these lecture 2020-07-01 Maxwell's equations are normally taken to be four in number, but in relativity using the antisymmetric tensor, can be best understood as two. Even those can be combined into one, using Clifford Algebra, but that's going somewhat off topic, except to note that the one feature of all of Maxwell's equations is that they are about derivatives of the field.

We can now put all of the field equations together, in both integral and local form, to construct a complete theory of electromagnetism. It is summarized in four equations, now known as Maxwell's equations: Figure 5.5.2 – Maxwell's Equations In essence, one takes the part of the electromagnetic force that arises from interaction with moving charge (q\mathbf {v} qv) as the magnetic field and the other part to be the electric field. Gauss's law: The earliest of the four Maxwell's equations to have been discovered (in the equivalent form of Coulomb's law) was Gauss's law.

Coulombs law can be derived from Maxwell's equations. The third equation is commonly known as Faraday's Law of electromagnetic induction and it states that a changing electric flux produces a magnetic field.
