Is magnetic field is produced by uniformly moving charge?

In summary: They are both caused by the motion of the charge. In summary, the conversation discusses the relationship between magnetic fields and moving charges. It is stated that a stationary charge has no magnetic field, but when it is in motion, a magnetic field is produced. This is due to the Lorentz transformation, meaning that the magnetic field is dependent on the observer's frame of reference. It is also mentioned that the electric and magnetic fields are both affected by the motion of the charge, but they do not affect each other.

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.
 

1. What is a magnetic field?

A magnetic field is a physical phenomenon that is produced by the motion of electric charges. It is a region in space where magnetic forces act on other moving charges.

2. How is a magnetic field produced by a uniformly moving charge?

A magnetic field is produced by a uniformly moving charge through the interaction between the electric and magnetic fields. As the charge moves, it creates an electric field, which in turn creates a magnetic field that surrounds the charge.

3. Is a magnetic field always produced by a uniformly moving charge?

No, a magnetic field is only produced by a uniformly moving charge if the charge is moving at a constant speed. If the charge is accelerating, it will also produce an electric field, but the resulting magnetic field will be more complex.

4. How does the strength of the magnetic field produced by a uniformly moving charge depend on the charge's speed?

The strength of the magnetic field produced by a uniformly moving charge is directly proportional to the charge's speed. This means that as the speed of the charge increases, the strength of the magnetic field also increases.

5. Can a magnetic field be produced by a stationary charge?

No, a magnetic field can only be produced by a moving charge. A stationary charge does not produce a magnetic field, but it can be affected by an external magnetic field.
