Electromagnetism

How far in math are you? are you familiar with the del operator?

can any one describe how this two are inter related and how can we describe the creation of one with change in other?

the magnetic field around a current carrying wire arises because special relativity makes the charge density appear to be inhomogeneous

You have a degree in Physics, then, or equivalent qualifications?

I have an engineer background on the subject of Physics and a far more detail knowledge of Maxwell equations due to my degree being in electronic.

An of course I am aware by reason of personal interests in the history of science as a whole and the attempts to achieved a UFT dating back to Einstein works in this area in the 1950s.

Now Brandon what is your background to claimed that there is now an existing UFT that is accepted to any degree.

Two physics degrees. Just go to the link.

You have two physics degrees and are claiming that there is a UFT that is accepted currently?

Must had missed that announcement in the Science American magazine!!!!!!!

Like I said, the four fundamental forces are electric, gravitational, strong nuclear, and weak nuclear. The magnetic force isn't even a fundamental force

LOL and like I am saying there is no accepted UFT currently and Maxwell field equations are used to express the relationships between electric and magnetic fields an it have zero repeat zero to do with Einstein relativity that anyone to date had shown at least.

relativity makes the existence of magnetic fields an inevitable consequence of the existence of electric fields. In the inertial system B moving relatively to the inertial system A, purely electric fields from A will look like a combination of electric and magnetic fields in B. According to relativity, both frames are equally fit to describe the phenomena and obey the same laws.

So special relativity removes the independence of the concepts (independence of assumptions about the existence) of electricity and magnetism. If one of the two fields exists, the other field exists, too. They may be unified into an antisymmetric tensor, Fμν.

However, what special relativity doesn't do is question the independence of values of the electric fields and magnetic fields. At each point of spacetime, there are 3 independent components of the electric field E→ and three independent components of the magnetic field B→: six independent components in total. That's true for relativistic electrodynamics much like the "pre-relativistic electrodynamics" because it is really the same theory!

Magnets are different objects than electrically charged objects. It was true before relativity and it's true with relativity, too.

It may be useful to notice that the situation of the electric and magnetic fields (and phenomena) is pretty much symmetrical. Special relativity doesn't really urge us to consider magnetic fields to be "less fundamental". Quite on the contrary, its Lorentz symmetry means that the electric and magnetic fields (and phenomena) are equally fundamental. That doesn't mean that we can't consider various formalisms and approximations that view magnetic fields – or all electromagnetic fields – as derived concepts, e.g. mere consequences of the motion of charged objects in spacetime. But such formalisms are not forced upon us by relativity.
