The correct Answer is:
To solve the question, we need to evaluate each statement related to magnets and determine which ones are correct. ### Step-by-Step Solution: 1. **Evaluate Statement (i)**: "In magnet there are always two magnetic poles." - A magnet, by definition, has two poles: a north pole and a south pole. This statement is correct. 2. **Evaluate Statement (ii)**: "There is a mutual attraction between like poles." - Like poles (north-north or south-south) repel each other, while opposite poles (north-south) attract each other. Therefore, this statement is incorrect. 3. **Evaluate Statement (iii)**: "A magnet which is independently hanged, always stops in geographically north-south direction." - A freely suspended magnet aligns itself in the north-south direction due to the Earth's magnetic field. This statement is correct. 4. **Evaluate Statement (iv)**: "If any magnet is cut down in many pieces then every piece will react as a complete magnet." - When a magnet is cut, each piece will have its own north and south pole, effectively making each piece a smaller magnet. This statement is correct. ### Conclusion: The correct statements are: - (i) In magnet there are always two magnetic poles. (Correct) - (ii) There is a mutual attraction between like poles. (Incorrect) - (iii) A magnet which is independently hanged, always stops in geographically north-south direction. (Correct) - (iv) If any magnet is cut down in many pieces then every piece will react as a complete magnet. (Correct) Thus, the correct answer is **C**: Statements (i), (iii), and (iv) are correct.
