Can quantum mechanics explain Maxwell s equations?

If you want to know the relationship between quantum and electromagnetic phenomena, go to quantum field theory or quantum electrodynamics (QED), because the Maxwell equation is a classical field equation, then you can see how electromagnetic phenomena are quantized after reading quantum field theory, and then understand that its classical limit is Maxwell theory.

We recommend that you read Weinberg's Quantum Field Theory, which is bible in this regard

What do you mean? Maxwell equations are theories that describe electromagnetism, Maxwell equations + present equations + Lorentz force that can be used to summarize all the fundamental electromagnetic phenomena in simple terms.

Do you want to know how the Maxwell equation came about?

Of course, the Maxwell equation does not come into being in a vacuum, and it can be derived in a variety of ways.

1. Deduced by three experimental laws: Coulomb's law, Ampere's law, and Faraday's law of electromagnetic induction.

2. Inductive electromagnetic phenomena are obtained, electrostatic field, static magnetic field, and constitutive equation.

3. Through the idea of field, the four-dimensional Lagrangian equation is introduced, and the idea of covariance is applied to add the electrostatic field (Coulomb's law).

As for the relationship between quantum mechanics and Maxwell's equations. Basically, it doesn't really matter, quantum mechanics is about the microscopic world, and maxwell is about macroscopic electromagnetic phenomena, so it doesn't and can't have anything to do with it.

If you want to learn the Maxwell equation systematically, then you can go to electromagnetism, and then you can read electrodynamics.

Quantum mechanics has included Maxwell's equations and so on in its own theory, while superstring theory has included all mechanics.

Maxwell's equationsIt is made up of four equations:

1. Gauss's law.

This law describes the relationship between the electric field and the distribution of charges in space. The electric field lines start with a positive charge and end at a negative charge (or infinity). Counting the number of electric field lines passing through a given closed surface, i.e., its electric flux, gives you an idea of the total charge contained in that closed surface.

In more detail, this law describes the relationship between the flux through any closed surface and the charge within that closed surface.

2. Gauss's law of magnetism: This law shows that magnetic monopoles do not actually exist in fast selling liquid. So, there is no isolated magnetic charge, and the magnetic field lines have no initial point and no end point.

The magnetic field lines form a cycle or extend to infinity. In other words, the magnetic field lines entering any area must leave that area. In terminology, the magnetic flux through an arbitrarily closed surface.

is equal to zero, or, the magnetic field is a passive field.

3. Faraday.

Induction Law: This law describes how a time-varying magnetic field induces an electric field. Electromagnetic induction is the theoretical basis for the manufacture of many generators. For example, a rotating bar magnet generates a time-varying magnetic field, which in turn generates an electric field that causes a nearby closed circuit to induce a current.

4. Maxwell-Ampère's law: This law states that magnetic fields can be generated in two ways: one is by conducting current (the original Ampère's law), and the other is by time-varying electric field, or displacement current (Maxwell's modifier).

Introduction to Maxwell's Equations:

It was the British physicist James Clark Maxwell.

A set of partial differential equations established in the 19th century to describe the relationship between electric and magnetic fields and charge density and current density. It consists of four equations: Gauss's law, which describes how electric charges produce electric fields, Gaussian magnetism, which states that magnetic monopoles do not exist, Maxwell's-Ampère's law, which describes how electric currents and time-varying electric fields produce magnetic fields, and Faraday's law of induction, which describes how time-varying magnetic fields produce electric fields.

From Maxwell's square acre group, electromagnetic waves can be deduced.

It travels at the speed of light in a vacuum, and then makes the conjecture that light is an electromagnetic wave. Maxwell's equations and the Lorentz force.

The equation is the fundamental equation of classical electromagnetism. From the relevant theories of these basic equations, modern power technology and electronic technology have been developed.

Maxwell's original form of equation defeat in 1865 consisted of 20 equations and 20 variables. He experimented with quaternions in 1873.

to express, but unsuccessfully. The mathematical form in use today was reformulated in 1884 by Oliver Heaviside and Josiah Gibbs in the form of vector analysis.

Maxwell's equations are to electromagnetism what Newton's laws of motion are to mechanics. The theory of electromagnetism, with Maxwell's equations at its core, is one of the proudest achievements of classical physics. Maxwell also contributed to the creation of the field concept, which was a great innovation in physics at the time.

From Maxwell's equations, it can be deduced that electromagnetic waves propagate at the speed of light in a vacuum, and then make the conjecture that light is electromagnetic waves. Maxwell's equations and Lorentz force equations are the basic equations of classical electromagnetism, from which modern power technology and electronic technology have been developed.

Maxwell's equations are made up of four equations, namely Gauss's law, Gauss's magnetosphere law, Faraday's law of induction, and Maxwell-Ampère's law. Gauss's law describes the relationship between the electric field and the distribution of charges in space; Gauss's law of magnetism states that magnetic monopoles do not actually exist; Faraday's law of induction describes how a time-varying magnetic field induces an electric field; Maxwell's Ampère law states that magnetic fields can be generated in two ways, one by conducting currents, the original Ampere-defined difference bright law, and by time-varying electric fields, or displacement currents, which are Maxwell's modified mark-up terms.

Maxwell's equations, why are they called the greatest formulas in human history?
