Which of the following properties is False for a bar magnet ?

Options

A. It doesn't produce magnetic field
B. Its like poles repel and unlike poles attract
C. Its poles cannot be separated
D. It points in North - South direction when suspended

Answer

To determine which property is false for a bar magnet, we will analyze each of the given properties step by step.

### Step 1: Analyze the first property
**Property A:** "It does not produce magnetic field."

- A bar magnet indeed produces a magnetic field. The magnetic field lines emerge from the North Pole and terminate at the South Pole. Therefore, this statement is false.

### Step 2: Analyze the second property
**Property B:** "Like poles repel each other and unlike poles attract each other."

- This statement is true. When two North poles or two South poles are brought close together, they repel each other. Conversely, a North pole and a South pole attract each other.

### Step 3: Analyze the third property
**Property C:** "Its poles cannot be separated."

- This statement is also true. If you cut a bar magnet, each piece will still have a North and a South pole. The poles cannot be isolated; instead, new poles are formed.

### Step 4: Analyze the fourth property
**Property D:** "When suspended, it points in the North-South direction."

- This statement is true as well. A freely suspended bar magnet aligns itself along the Earth's magnetic field, pointing towards the geographic North and South.

### Conclusion
After analyzing all properties:
- Property A is the only false statement regarding a bar magnet.

### Final Answer
The false property for a bar magnet is **A: It does not produce magnetic field.**
