Moving charges have:
Correct answer: A. Electric field and magnetic field both
- A. Electric field and magnetic field both
- B. None of these
- C. Magnetic field only
- D. Electric field only
Explanation
A moving charge generates both an electric field and a magnetic field. The electric field is due to the charge itself, as any charged particle will create an electric field in its surroundings. When the charge is in motion, it also generates a magnetic field, as moving charges are a source of magnetic fields according to electromagnetic theory. Therefore, the correct answer is that moving charges have both electric and magnetic fields.

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.
