The universal proporty among all substance is

Options

A. diamagnetism
B. paramagnetilsm
C. ferromagnetism
D. non magnetism

Explanation

To solve the question regarding the universal property among all substances, we will analyze the different types of magnetic properties and determine which one is applicable universally.

### Step-by-Step Solution:

1. **Understanding Magnetic Properties**:
- There are different types of magnetic materials: diamagnetic, paramagnetic, and ferromagnetic.
- Each type has distinct behaviors in the presence of a magnetic field.

2. **Defining Diamagnetism**:
- Diamagnetic materials are characterized by their ability to be repelled by a magnetic field.
- When a magnetic field is applied, diamagnetic materials induce a magnetic field in the opposite direction, resulting in a repulsive force.

3. **Defining Paramagnetism**:
- Paramagnetic materials are attracted to a magnetic field.
- They have unpaired electrons that align with the external magnetic field, enhancing the magnetic effect.

4. **Defining Ferromagnetism**:
- Ferromagnetic materials also exhibit attraction to magnetic fields.
- They have regions called magnetic domains that can become aligned in the presence of a magnetic field, resulting in a strong magnetic effect.

5. **Identifying the Universal Property**:
- Among these properties, diamagnetism is unique because it is present in all materials, regardless of their other magnetic properties.
- Every substance, to some extent, exhibits diamagnetism, even if it is not the dominant property (as in the case of ferromagnetic or paramagnetic materials).

6. **Conclusion**:
- Therefore, the universal property among all substances is **diamagnetism**. This property remains unchanged regardless of the material's other magnetic characteristics.

### Final Answer:
The universal property among all substances is **diamagnetism**.
