If magnetic susceptibility of a certain magnetic material is 0.0001, find its relative permeability. 

Explanation

To find the relative permeability (\( \mu_r \)) of a magnetic material given its magnetic susceptibility (\( \chi_m \)), we can use the relationship between the two. Here’s the step-by-step solution:

### Step-by-Step Solution

1. **Identify the Given Value**:
The magnetic susceptibility (\( \chi_m \)) is given as \( 0.0001 \).

2. **Use the Formula for Relative Permeability**:
