Question

A moving electron produces

• A. only electric filed
• B. both electric and magnetic field
• C. only magnetic field
• D. neither electric nor magnetic field

Answer 1

The Correct Option is B

An electron is a charged particle, so it naturally produces an electric field. When the electron moves, it constitutes an electric current, and moving charges generate a magnetic field as per Ampère’s law.

Therefore, a moving electron produces:

• An electric field (due to its charge)
• A magnetic field (due to its motion)

A moving electron produces both electric and magnetic fields. Hence, the correct answer is \({\text{B}} \).

Answer 2

A moving electron produces both an electric field and a magnetic field.

Electric Field:

• Caused by the charge of the electron.
• Exists whether the electron is at rest or moving.

Magnetic Field:

• Arises due to the motion of the electron (the moving charge acts like a current).
• The direction of the magnetic field is determined by the right-hand rule.

The electric and magnetic fields are interconnected in the theory of electromagnetism.

These behaviors are described by Maxwell’s equations.
