Choose the wrong statement:

Options

A. magnetic poles always exist in pairs
B. magnetic poles are always of equal strengths
C. like poles repel each other
D. unlike poles repel each other

Answer

To solve the question of identifying the wrong statement among the given options regarding magnetic poles, we will analyze each statement step by step.

### Step 1: Analyze Statement 1
**Statement:** Magnetic poles always exist in pairs.
**Analysis:** This statement is true. Every magnet has a north and a south pole. If you cut a magnet, you do not create a monopole; instead, you create two smaller magnets, each with its own north and south pole. Therefore, this statement is correct.

### Step 2: Analyze Statement 2
**Statement:** Magnetic poles are always of equal strength.
**Analysis:** This statement is also true. The strength of the north pole is equal to the strength of the south pole. They have the same magnitude of magnetic force, just opposite in direction. Hence, this statement is correct.

### Step 3: Analyze Statement 3
**Statement:** Like poles repel each other.
**Analysis:** This statement is true. When two north poles or two south poles are brought close together, they repel each other. Therefore, this statement is correct.

### Step 4: Analyze Statement 4
**Statement:** Unlike poles repel each other.
**Analysis:** This statement is false. Unlike poles (one north and one south) attract each other. Therefore, this statement is incorrect.

### Conclusion
The wrong statement among the options is **Statement 4: Unlike poles repel each other.**

### Final Answer
**The wrong statement is:** Unlike poles repel each other (Option 4).
