Question

Consider the following statements:

Identify the correct statements.

• A. Only 1 and 2
• B. Only 2 and 3
• C. Only 1 and 3
• D. All the three

Answer 1

The correct option is D All the three

All the given statements are correct. A compass is an instrument used to identify the directions. It uses a freely suspended magnetic needle that rests in the North-South direction. The needle of a magnet aligns itself in the direction of the Earth's magnetic field at that point.
However, when a strong magnet is brought close to the compass, the magnetic needle aligns itself in the direction of the magnetic field of the strong magnet. That direction may not always be the North-South direction in the presence of an external magnetic field.
