What is the reason for electron to create magnetic field?

friction

Friction? Interesting idea. How about moving in vacuum?

No such thing as a vacuum at the qm scale.
Or any other scale ( if an 'absolute vacuum' is your proposal)

Quantum mechanics shows us that vacuum is a crude misnomer and is not per se "empty" and defined in terms of energy state, ignoring the 'philosophical' tripe on the lexical scoping, leading to some form of conclusion that absolute vacuum = absolute nothing.

Could you please make clearer your answer for dilettante like me: What do you mean under friction. If it means induction vortex fields during electron’s moving, so it is not ohmic loss. And “dirty vacuum” don’t disturb electron on its orbit in the atom.

Friction isn't right. Basically a moving electron creates a current, and the current or the change in electric field concurrently generates a magnetic field.

For classical electrodynamics as well as for special relativity what you are looking for can be found n Maxwell's equation: http://farside.ph.utexas.edu/teaching/em/lectures/node48.html

Magnetic fields and electric fields are observer-dependent manifestations of the same phenomenon.

The simple, not too exciting answer is that a magnetic field is produced when you have a moving charge, aka a current. I'm not sure if it can be explained any deeper than that in simplicity.

Agreed. Electro-magnetism is a unified phenomenon like two sides of the same coin. Are electrons ever considered "to exist at rest"?

You right. Thanks for link.

It is meant that electrons' drift speed is zero. Maybe electrons on the charged metal surface are immovable.

Yes, but I understand electrons as "wave packets" or three dimensional nodes of reinforcement of electro-magnetic waves. "Lack of drift" implies "standing waves" rather than the exclusion of e.m. wave dynamics. Presumably "at rest" would be observer relative, rather than absolute, so observed field effects would also be relative. In any event "creation" or "cause" are lay-concepts which have no ultimate meaningful status in physics.

You understand electron/s?
Nice one:)

Why did you bother to answer the question in the first place, if you didn't understand electron/s?
Friction... are you kidding me?

LOL dude, you know he is right any way, without friction the process snaps and you know it.

LOL hombre loco, you know he is wrong and you are wrong anyway, and friction encountered by electrons can cause the material which the electrons are moving to generate heat, for example, friction encountered by electrons generating heat in a conductor. Friction is a force resisting relative movement of something caused by the interactions taking place at the contact between things. Magnetic interaction and the spin of electrons can contribute to friction in a given application, but friction does not contribute to magnetic interaction. Friction can indeed cause attraction between dissimilar (diaelectic) materials, but the phenomenon is electrostatic, not magnetic.

You do understand basic cause and effect quite clearly, yet you attempt to deny energy displacement factors, heat exchange alters and even expands magnetic fields, perhaps even creates them at the extremes of the wire, rather than a loop internal which the lack of friction would allow a space to fill of significant value.

Particularly given heat is transferred to EM through spacial dispersal as a deteriorating force.

As evidenced by superconductivity and its state of hyper flow.

LOL Your current post is in contradiction with your previous post, hombre loco.
The question asks What is the reason for electron to create magnetic field? friction is not even related to the creation of magnetic field, and it is only related in the sense that it can affect the strength of magnetic field, but, I repeat, it is not the reason for electrons to create magnetic field.
As you mentioned, heat does affect magnetic properties of an object. The higher the temperature of an object gets,the atoms gain more kinetic energy and move around more rapidly thus the magnetic domain is disturbed. Thusly, the superconductors, you mentioned, run best on very low temperatures, cooled below critical temperatures.Increased cold work as well as low quantities of impurity additions systematically reduce the strain amplitude of the internal friction of super conducting wire making it possible to create superconducting magnets.

It is not a contradiction at all to suggest a theory such as absent variable, you see that the supposition is broken, thus believe I am wrong, pull your head back in.

Twice you have insulted me, Killmore who died twice today.

A theory which you pulled out of your ass, I'm sure. Pull your **** together first before you talk, hombre loco.
