Why do electrons produce a magnetic field? (According to special relativity theory)?

They AREelectromagnetic waves---and particles at the same time,---Just as Energy and Matter are the same thing,If they move parallel to us in a 4th dimensional direction (time)--they are solid If they move at right angles to us in time they are electromagnetic energy,The ratio to mass energy aspect depends upon the angle -0 to 90 degrees-- they move from the observer.You dont need special relativity.The electron has spin - it revolves around an aixs.......
I tried to find an answer for this question, but I still don't understand because I haven't found any good explanation for my question.

Because of the angle from which we OBSERVE them. They ARE electromagnetic waves---and particles at the same time,---Just as Energy and Matter are the same thing,

If they move parallel to us in a 4th dimensional direction (time)--they are "solid" If they move at right angles to us in time they are electromagnetic energy, The ratio to mass energy aspect depends upon the angle -0 to 90 degrees-- they move from the observer.

You don't need special relativity. The electron has spin - it revolves around an aixs. Since the electron has a negative electrical charge, and the charge is moving, then by Ampere's Law (one of Maxwell's equations) there is a magnetic field. To compute the value of the electron's magentic moment accuracte you need to employ quantum electrodynamics which incorporates special relativity, but the basic physics does not require special relativity.

Now maybe your question is more along the lines of use special relativity to explain why mvoing charges produce a magnetic field. Then the argument goes like this. Assume teh charges move at constant speed (special relativity requires constant speed). Now transform reference frames so that you are moving along with them. All you see are electric fields due to the charges. Now Lorentz transform back into the laboratory (rest frame) frame of reference where you are at rest and the charges are moving. The Lorentz transformation is a rotation ins space-time so some of the electric field you saw in the co-moving reference frame now transforms into magnetic fields and those fields are precisely what Ampere's Law you give you.
