The permeablitiy of paramgentic substance is

Options

A. slinght more than vacuum
B. slight less than vacuum
C. much more than vaccum
D. None of the above

Answer

To determine the permeability of a paramagnetic substance, we can follow these steps:

### Step 1: Understand the concept of permeability
Permeability (μ) is a measure of how easily a magnetic field can penetrate a material. It is defined relative to the permeability of free space (vacuum), which is denoted as μ₀.

### Step 2: Define paramagnetic substances
Paramagnetic materials are those that have a small, positive susceptibility to magnetic fields. This means they are weakly attracted to magnetic fields and exhibit a slight increase in magnetic permeability compared to vacuum.

### Step 3: Compare permeability of paramagnetic substances to vacuum
In vacuum, the permeability is defined as μ₀. For paramagnetic substances, the permeability (μ) is slightly greater than μ₀. This is because when a paramagnetic material is placed in a magnetic field, the magnetic field lines are weakly attracted and can pass through the material more readily than through vacuum.

### Step 4: Analyze the options given in the question
- Slightly more than vacuum: This option aligns with our understanding of paramagnetic materials.
- Slightly less than vacuum: This is incorrect since paramagnetic materials have a positive susceptibility.
- Much more than vacuum: This is also incorrect, as paramagnetic materials do not exhibit a strong magnetic response.
- None of the above: This option is incorrect based on the previous analysis.

### Step 5: Conclusion
Based on the analysis, the permeability of a paramagnetic substance is slightly more than that of vacuum.

### Final Answer
The permeability of a paramagnetic substance is slightly more than vacuum.
