Q32 · 1 mark · Assertion-reasonCompetency-basedMagnetic Effects of Electric Current

For question number 32, two statements are given – one labelled as Assertion (A) and the other labelled as Reason (R). Select the correct answer to this question from the codes (A), (B), (C) and (D) as given below.

Assertion (A): The needle of a magnetic compass kept in strong external magnetic field, always aligns itself in north-south direction on the earth.

Reason (R): Behaviour of the needle of a compass is same as that of a freely suspended bar magnet.

  1. (A)Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
  2. (B)Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
  3. (C)Assertion (A) is true, but Reason (R) is false.
  4. (D)Assertion (A) is false, but Reason (R) is true.

Hints

Open one hint at a time and try again before the next.

Hint 1

Which field does a compass needle follow?

Hint 2

If a strong magnet is placed near a compass, what happens to the needle?

Step-by-step solution

Each step shows the marks it earns, as an examiner would award them. Checked by an independent re-solve from the question paper.

  1. A is false: in a strong external magnetic field the needle aligns along that field, not along the earth's north-south direction.

  2. R is true: a compass needle is a small magnet and behaves like a freely suspended bar magnet. Answer: (D).

    1 mark

Answer: (D)

Where the marks are

  • A false, R true (1 mark)
