If `mu_(0)` is absolute permeability of vacum and `mu_(r)` is relative magnetic permeability of another medium , then permeability `mu` of the medium

Options

A. `mu_(0)mu_(r)`
B. `mu_(0)//mu_(r)`
C. `mu_(r)//mu_(0)`
D. `1//mu_(0)mu_(r)`

Explanation

To find the permeability \( \mu \) of a medium given the absolute permeability of vacuum \( \mu_0 \) and the relative magnetic permeability \( \mu_r \), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definitions**:
- The absolute permeability of vacuum \( \mu_0 \) is a constant that represents the permeability of free space.
- The relative magnetic permeability \( \mu_r \) is a dimensionless quantity that represents how much more or less permeable a medium is compared to vacuum.

2. **Write the Formula for Relative Permeability**:
- The relationship between the relative permeability \( \mu_r \) and the absolute permeability \( \mu \) of the medium is given by:
\[ \mu_r = \frac{\mu}{\mu_0} \]

3. **Rearrange the Formula**:
- To find the absolute permeability \( \mu \) of the medium, rearrange the formula:
\[ \mu = \mu_r \cdot \mu_0 \]

4. **Conclusion**:
- Therefore, the permeability \( \mu \) of the medium can be expressed as:
\[ \mu = \mu_r \cdot \mu_0 \]

### Final Answer:
The permeability \( \mu \) of the medium is given by:
\[ \mu = \mu_r \cdot \mu_0 \]
