Question
An electric charge in motion produces
- An electric field only
- A magnetic field only
- Both electric and magnetic fields
- No field
Hint:
- An electric charge applies a coulomb force in all three dimensions on other charges which is felt by other charges in the form of an electric field electric field. The fields of electricity and magnetism are interlinked with each other. In fact, a changing electric field gives rise to a changing magnetic field and vice versa.
The correct answer is: Both electric and magnetic fields
- An electric charge always exerts a force known as the Coulomb force in all three dimensions upon other electrical charges. This force is felt by the other charged particles as the effect of an electrical field that originates from the first charge and travels through the medium in the form of a wave to reach them.
- This electric force and, hence, electric field is produced by an electrical charge irrespective of its motion.
- An electric charge in motion is nothing but electric current. This produces a magnetic field.
- Hence, the electric charge in uniform motion produces both electric and magnetic fields.
