The magnetic strength of a magnet

Options

A. is uniform throughout the body of the magnet
B. is concentrated at one point called the pole of the magnet
C. is concentrated at the two ends of the magnets called the poles of the magnet.
D. is concentrated in the centre of the magnet.

Answer

### Step-by-Step Text Solution

1. **Understanding the Structure of a Magnet**:
- A magnet has two poles: the North pole and the South pole. These are the ends of the magnet where the magnetic strength is the greatest.

2. **Magnetic Strength Distribution**:
- The magnetic strength of a magnet is not uniform throughout its entire body. It varies depending on the location on the magnet.
- At the poles (the ends of the magnet), the magnetic strength is maximum.
- At the center of the magnet, the magnetic strength is minimum.

3. **Evaluating the Options**:
- **Option 1**: "It is uniform through the body of the magnet."
- This is incorrect because the magnetic strength is not uniform; it varies from maximum at the poles to minimum at the center.
- **Option 2**: "It is concentrated at one point called the pole of the magnet."
- This is also incorrect because the magnetic strength is concentrated at both ends (the North and South poles), not just one point.
- **Option 3**: "It is concentrated at the two ends of the magnet called the poles of the magnet."
- This is correct. The magnetic strength is indeed concentrated at the two ends of the magnet.
- **Option 4**: "It is concentrated in the center of the magnet."
- This is incorrect because the center has the minimum magnetic strength.

4. **Conclusion**:
- The correct answer is **Option 3**: "It is concentrated at the two ends of the magnet called the poles of the magnet."
