........ is the space around a magnet where magnetic effect can be felt.

Answer

**Step-by-Step Solution:**

1. **Understanding the Concept of Magnetism:**
- A magnet has two poles: North and South. These poles create a magnetic effect in the surrounding space.

2. **Defining the Space Around a Magnet:**
- The area around a magnet where its magnetic influence can be felt is known as the magnetic field.

3. **Identifying the Characteristics of the Magnetic Field:**
- The magnetic field is invisible but can be detected using magnetic materials or instruments like a compass.

4. **Illustrating the Effect of the Magnetic Field:**
- When a compass is brought near a magnet, the needle of the compass aligns itself with the magnetic field lines, indicating the presence of the magnetic field.

5. **Conclusion:**
- Therefore, the space around a magnet where its magnetic effect can be felt is called the **magnetic field**.

**Final Answer:**
The space around a magnet where magnetic effect can be felt is called the **magnetic field**.
