Is magnetic field is produced by uniformly moving charge?is it affect it,s magnetic field?
Is Magnetic field of charge is due to relative motion?

Hi waqarrashid33! :wink:

A stationary charge, as you know, has no magnetic field.

In any other frame, it does have a magnetic field (and its electric field also changes), in accordance with the Lorentz trannsformation.

In other words, a charge moving relative to the observer (even uniformly moving) has a magnetic field. :smile:

Let suppose a man have charge in his hand and runing the he will not feel the magnetic field field of charge by a compass and a man standing near to him will detect the magnetic field by his compass?

That's right! :smile:

If the charge is at rest, then any observer in the same frame will not see a magnetic field. Only those that see a moving charge have a chance to see magnetic field produced by this charge.

even if the moving charge is accelerating??

As long as it's moving, it has a magnetic field. The instances, if any, in which v = 0, this is not the case. As you may be aware of, the field strength og the magnetic field is linearily proportional to the speed.

THE production of magnetic affect the E.field of the charge?

The magnetic field and the electric field are both affected by the same thing: the motion of the charge.

The magnetic field and the electric field do not affect each other.
