Electric charge in uniform motion produces:
Correct answer: C. Both option A and B
- A. Electric field
- B. Magnetic field
- C. Both option A and B
- D. None of these
Explanation
An electric charge in uniform motion produces both electric and magnetic fields.A stationary electric charge produces only an electric field. However, a moving electric charge produces both an electric field and a magnetic field. The electric field is produced by the charge's static electric field, while the magnetic field is produced by the charge's moving electric field.The strength of the electric field produced by a moving charge is proportional to the charge's magnitude and its speed. The direction of the electric field is perpendicular to the direction of the charge's motion.The strength of the magnetic field produced by a moving charge is proportional to the charge's magnitude, its speed, and its perpendicular distance from the field point. The direction of the magnetic field is perpendicular to both the direction of the charge's motion and the direction from the charge to the field point.The following are some examples of electric charges in uniform motion that produce both electric and magnetic fields:A charged particle moving through a vacuumA current-carrying wireA rotating magnet

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
