Question

The needle of a compass is made up of a magnet. Which of the following statements can prove it?

• A. The needle attracts objects made of magnetic materials.
• B. The needle gets deflected when it is brought near a magnet.
• C. The needle comes to rest in the East-West direction.
• D. The needle comes to rest in the North-South direction.

Answer 1

Answer: (A), (B), (D)

The needle comes to rest in the North-South direction.

The needle of a magnetic compass attracts or repels other magnets, and is also deflected in their presence. It attracts or repels magnetic materials and comes to rest in the North-South direction in the absence of magnets. Thus, it shows all the properties that a bar magnet possesses. Therefore, it can be proven that it is made up of a magnetic substance.
