Which of the following is universal magnetic property

Options

A. Ferromagnetis
B. Diamagnetism
C. Pararnagnetis
D. Anti-ferromagnetism

Explanation

To determine which of the following is a universal magnetic property, we can analyze the different types of magnetic properties that exist in materials.

### Step-by-Step Solution:

1. **Understanding Magnetic Properties**:
- There are several types of magnetic properties: diamagnetism, paramagnetism, and ferromagnetism. Each of these properties behaves differently in the presence of a magnetic field.

2. **Defining Diamagnetism**:
- Diamagnetism is a property exhibited by all materials, where they create an opposing magnetic field when exposed to an external magnetic field. This results in a very weak repulsion from the magnetic field.

3. **Characteristics of Diamagnetic Materials**:
- Diamagnetic materials are characterized by their weak magnetic response. They are not attracted to magnets; instead, they are weakly repelled. This property is present in all materials, regardless of their other magnetic characteristics.

4. **Comparison with Other Magnetic Properties**:
- Paramagnetism and ferromagnetism are not universal properties. Paramagnetic materials are attracted to magnetic fields but only in the presence of an external field, and ferromagnetic materials can retain magnetization. Not all materials exhibit these properties.

5. **Conclusion**:
- Since diamagnetism is the only magnetic property that is universally present in all materials, it can be concluded that the universal magnetic property is diamagnetism.

### Final Answer:
The universal magnetic property is **Diamagnetism**.
