Question

Study the given statements and identify the correct ones:
(i) A magnetic compass is used to show the directions.
(ii) The needle of a magnetic compass is magnetic.
(iii) The needle of a magnetic compass always aligns with the north and the south directions of the earth.

• A. Only (i)
• B. Only (ii) and (iii)
• C. Only (i) and (iii)
• D. All the three

Answer 1

The correct option is D All the three

All the given statements are correct.
A magnetic compass is an instrument used to determine the directions. It uses a freely rotating magnetized needle that indicates north-south direction. The earth also acts as a magnet and interacts with other magnets present in its field. Thus, the north pole of a magnet needle gets attracted to the Earth's magnetic south pole (which is geographical north pole of the earth).
