Do magnetic monopoles exist? [duplicate]

According to Gauss's law in magnetism, we know that there is no magnetic monopoles. But my teacher told in the class that magnetic monopoles exists but he didn't told us where instead told to search ...

Where did the idea that there *might* be magnetic monopoles come from? [duplicate]

I know that we declare that there exist no magnetic monopoles. I see it all the time in my E&M class. $$\vec{\nabla}\cdot\vec{B}=0$$ So there exists no point for $\vec{B}$ to originate from and no ...

Why can't a particle that carries magnetic charge exist? [duplicate]

Electron is the source of electric field and changing electric field produce magnetic force, what about particle that can do vice versa? My concern is how come universe favors particles that carry ...

Does magnetic monopoles really exist? [duplicate]

I have found out some research going at CERN (LHC) . Is it true that monopoles behave like electrons or protons? and thus prove quantization of charge?

Can Maxwell's equations be derived from Coulomb's Law and Special Relativity?

As an exercise I sat down and derived the magnetic field produced by moving charges for a few contrived situations. I started out with Coulomb's Law and Special Relativity. For example, I derived the ...

What is the explanation of the non-existence of magnetic monopoles? [closed]

Electric monopoles do exist, but why cannot magnetic monopoles exist? The question is closed because I need to clarify it, but I don't know how I could ask it another way. However, I've recieved ...

Is there a topological difference between an electric monopole and an magnetic monopole?

When we introduce magnetic monopoles, we have duality, i.e. invariance under the exchange of electric and magnetic fields. Magnetic (Dirac) monopoles are usually discussed using topological ...

Why do we like gauge potentials so much?

Today I read articles and texts about Dirac monopoles and I have been wondering about the insistence on gauge potentials. Why do they seem (or why are they) so important to create a theory about ...

Is the magnetic force real or illusion?

Reading this talk. Mind blown. It explains how the concepts of special relativity and length contraction between inertial reference frames converts magnetic forces to electrostatic forces depending on ...

What was Dirac's motivation to study hypothetical magnetic monopoles?

The equation $$\boldsymbol{\nabla}\cdot\textbf{B}(\textbf{r})=0\tag{1} $$ dictates that there can be no isolated magetic monopole. What was then the motivation for Dirac to consider the consequences ...

Magnetic monopole bound state

Magnetic monopole (mm) bound states Background: I'm an experimentalist, simple equations are appreciated. (Complicated equations are fine, as long as I can ask questions.) This is one of many ...

Why magnetic monopole has't been shown in the particle physics's Standard Model context?

For various reasons, experts, since Dirac, believe that a unified field theory must have a magnetic monopole. For example, Polyakov said: "I am quite certain that magnetic monopoles really exist. How, ...

Do the Maxwell equations definitively rule out the existence of magnetic monopoles?

Gauss's law for magnetism, $\nabla \cdot \mathbf {B} =0$, is most directly interpreted as a sort of Kirchhoff's current law for magnetism, stating that while magnetic fields can be drawn between ...

Do most physicists believe that axions exist? [closed]

Is the theoretical justification behind proposing axions sufficiently robust, like, say the Higgs boson prior to its detection, that one should consider the existence of axions as generally accepted (...

Is there a relation between (non-) existence of magnetic monopoles and thermodynamics?

This question follows on previous work on connections between (other) areas of physics and thermodynamics as in here, here and even here. P. Dirac (an electrical engineer initially) was one of the ...
