Liquid oxygen remains suspended between two pole faces of a magnet because it is

Options

A. a.Anti ferromagnetic
B. b.Ferromagnetic
C. c.Paramagnetic
D. d.Diamagnetic

Answer

To solve the question of why liquid oxygen remains suspended between two pole faces of a magnet, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: The question is asking about the magnetic properties of liquid oxygen and how it behaves in a magnetic field created by two pole faces of a magnet.

2. **Identify the Options**: The options given are:
- A) Anti-ferromagnetic
- B) Ferromagnetic
- C) Paramagnetic
- D) Diamagnetic

3. **Review Magnetic Properties**:
- **Ferromagnetic** materials have a very high magnetic susceptibility and can be permanently magnetized.
- **Paramagnetic** materials have a positive magnetic susceptibility but are not permanently magnetized; they are attracted to magnetic fields.
- **Diamagnetic** materials have a negative magnetic susceptibility and are repelled by magnetic fields.
- **Anti-ferromagnetic** materials have magnetic moments that align oppositely and cancel each other out.

4. **Analyze Liquid Oxygen**:
- Liquid oxygen (O2) is known to exhibit paramagnetic behavior. This means that it has unpaired electrons, which allows it to be attracted to a magnetic field.

5. **Determine the Correct Option**:
- Since liquid oxygen is paramagnetic, it will be attracted to the magnetic poles and can remain suspended between them. Therefore, the correct answer is C) Paramagnetic.

6. **Conclusion**: Liquid oxygen remains suspended between the two pole faces of a magnet because it is a paramagnetic substance.

### Final Answer:
Liquid oxygen remains suspended between two pole faces of a magnet because it is **paramagnetic**.
