Moving Charges and Magnetism

Question:

Consider the following statements:

(A) An emf can be induced by moving a conductor in a magnetic field.
(B) An emf can be induced by changing the magnetic field
(C) An emf can be induced by changing the electric field
(D) An emf can be induced by moving a conductor in an electric field

Choose the correct answer from the options given below:

Options:

(A), (B) and (D) only

(A) and (B) only

(A) and (C) only

(B), (C) and (D) only

Correct Answer:

(A) and (B) only

Explanation:

The correct answer is Option (2) → (A) and (B) only

According to Faraday's law of electromagnetic induction:

  • (A) True — Moving a conductor in a magnetic field induces emf.
  • (B) True — Changing the magnetic field induces emf.
  • (C) False — Changing electric field alone does not induce emf in a conductor.
  • (D) False — Moving a conductor in an electric field does not induce emf (unless magnetic effects are involved).

Correct statements: A and B
